The FTRPA September 2016 shoot in pictures

9/21/2016

2 Comments

 
The Falls Township Rifle and Pistol Association always puts up a great shoot.

Usually, it is not a difficult shoot, so people leave happy to have downed quite some targets, BUT, there are always those targets that are "separators" that prevent almost anyone from cleaning the course.
Curiously enough, the MD's (all 4 of them) at FTRPA have absolutely no problem with anyone cleaning the course. They would LIKE it!

This attitude comes from years of accumulated MD'ing. You EASILY approach the century of accumulated experience between the 4 of them.

So, my point is that the place is just beautiful, the courses are reasonable, and the competition very friendly. A very enjoyable morning of shooting metal critters with friends.

If you have never been to the club, you owe it to yourself to go there. It is an experience you will always remember.

The official report of the Match has been posted already here. But if you are like me, you will like to see pictures!  ;-)

Without further ado, here are some pictures from last weekend's match:

REDEMPTION

9/17/2016

5 Comments

 
The 2016 Pyramyd Air Cup (PAC) is over.

Almost 100 airgunners met at the Tusco Rifle Range in Dennison, OH, to battle the elements, themselves, and the MD’s cunning ways.

To say that it was a ton of fun would be a great understatement.
For the third year in a row the Pyramyd Air crew from the owners (Val and Josh) down, go all out to host what has become the most important Airgun Schützenfest of the year.

Other shoots are mostly, if not exclusively, FT oriented; none have the diversity of events, participants, and contests as the PAC. This is important to FT because the shoot draws people that wouldn't normally go to a ‘pure’ FT shoot and exposes them to the degree of shooting proficiency that is developed through FT.
One anecdote illustrates this:
A novel shooter approached one of the organizers and told him flat out that he was there to win the ‘Gunslynger’ (a speed shooting event that involves shooting at 1/10th scale metallic silhouettes at longer than normal silhouette distances).

He quickly lost his first round and so devoted some time to watch the other shooters in the FT course.
By the end of the day he came back to the same organizer to say: "I thought I could shoot but, dude, these guys REALLY know how to shoot, I’ll practice and come back next year"

Hopefully, the fun, camaraderie, and sportsmanship always present in FT will draw him into this, the most fun and challenging of airgun sports.

The sport has much to thank Pyramyd Air for its constant and unswerving support, both of this great event, and of FT Team USA

This year I owe the title word of this blog entry to my friend, Ken Hughes, undoubtedly one of the best FT’ers in the Nation. We both missed a 50’ish yard hornet, setup on a mast atop the range’s berm. And after the match was done, we met at the Hornet to try to bring it down with a well crafted shot (I had to take two more shots to finally elucidate what was happening with the wind at that height). It was then that he commented he had ‘redeemed' himself’.

That comment stuck in my mind all through both flights back home and, indeed, is the perfect title. So, thanks, Ken!

PREPARATION.- For me, the 2016 PAC started just after my return from Lisbon. My atrocious performance there justified an all out effort to do better this time and, so, my rifle received a new spring (by Titan Springs, now available in the US from Ct. Custom Airguns) with a custom made guide, and new seals; and we started the search for a more suitable pellet. Clearly the JSB 8.44 Exacts were not compatible enough with the barrel to give the necessary accuracy AND precision.

It was a race against the calendar. There was less than a month to get this done, and I only have an hour, maybe two, every other day available for these pursuits.
With patience and a disciplined method we tested what pellets we had on hand paired with different lubes to come up with the best combination possible.
This quest ended selecting the FT Premium 8.44 pellets from JSB at 790 fps with a VERY close second being the Express’s 7.9 at 820 fps.
Team USA had already tested the Premium pellets and results had been less than impressive but you have to approach each re-build as a completely different gun, so we tested them and now they surprised us.
The spring had already been under tests, and so, there was no question it had set and would be stable for a long time.
The guide, however, was different, and I wanted to put in at least 500 shots before the competition. By the time I arrived at Tusco Rifle Range I had about 200 shots with the new guide in an, yet, untested & new design.
But I was relatively confident. ½”  5 shot AVERAGE O-O groups at 35 yds (32 meters) from the FT position is nothing to sneeze at.
And so the trip started on Wednesday, when Veronika, Daniel and myself went to stay over the night in Brooklyn, where Veronika and Daniel were to spend the end of the week and the weekend with Oma and Opa.
I’m blessed in having a wife and in-laws that help as much as the Brooklyn to Connecticut distance allows and are always happy to have the grandson over for the weekend. This allows me to take less expensive flights out of NYC, as opposed to those that originate in Hartford, or White Plains.
Great thanks are owed by us shooters to those family members that, even if they do not understand our passion in detail, go out of their way to help us. So, thanks Oma and Opa!

By Thursday early morning I was at LGA airport checking-in the rifle to the usual astonishment of the girls at the counter and the unending mirth/scorn of the Port Authority police that sees our airguns as very expensive, and bothersome, toys.
Checking-in done, I resigned myself to an hour’s flight South to Atlanta, only to come North to Canton-Akron the same hour and change. Ah! The result of a late decision to come to the Cup and the ‘Hub’ structure of all airline route programs.
I will try to program better next year, but G’d knows I’m gonna be busier than the proverbial one legged man in an a** kicking contest.

I finally arrived into CAK and it took as long to rent the car as it took to fly from ATL to CAK!

By the time I rolled into New Philadelphia, everyone had had dinner and so, I found myself at the Texas Roadhouse having a steak.

Early next morning I started meeting other shooters at Denny’s and we all headed out to the range.

By noon, I was all sighted in and the trajectory surprised me. The resultant BC calculated by PP-Calc exceeded any expectations, but the results support the calculations. How can a short, chubby pellet have such an excellent ballistic coefficient can only be attributed to a good shape and a smooth, vibration free release from the barrel.
Now that I have a lot more shots, I am even happier about it as the consistency of these pellets across batches makes them a very good choice. I tested the trajectory and the POI with three different lots of Premium (a few that were left from the original Team USA test, a box I won at the 2016 Canadian Nationals' Raffle in Port Colborne, and a new lot purchased from Pyramyd Air, and the results were impressively consistent.

I still need to get them all out of their pretty packaging to lube, and then I am too lazy to put them back in, so I just dump them in a transport tin made with a 500 ct. 0.20 cal tin lined above, under and on the sides with protective foam.
I guess I need to make a shaker that will space and orient the pellets properly so that I can reinsert them into their protective packing that is excellent once cut to the 50x4 format of a World’s shoot.
Of course I will also need to do this with the Expresses, LOL! Never leave any stone unturned.

THE PAYDAY CHALLENGE.-The day wore on and the Payday Challenge came around.

This is a fun competition where you are given a gun, pre-sighted in by the MD for each of three stations.
Station 1 required 5 shots from the bench at a FT 40 yards away.

Next station required 3 shots at a FT at 25 yards, offhand.

Station 3 required 2 shots offhand at a FT that is 15 yards away.

In total, 10 shots.

Rifle for station 3 was an HW100; for station 2 was a TDR; for station 1 was a Condor.

It’s hard, if not impossible, to sight in a rifle for someone else with precision. Whether the shooter uses glasses or not, or if his eyes are a little more tired than the sighter-in or the angle of the face and how he holds the rifles, all factors that are important in being consistent when shooting precision riflery literally are different for every person. But it was all in good fun and the competition started.

I missed my first shot on the Station 2 standers, but the shot felt good and I used that info to correct the aim on the TDR for the next two shots, which hit the mark.

I then went on to the Condor of Station 3 and got those two shots.

When my turn came for Station 1, Tyler instructed me as to how to aim, same instructions as he was giving to everyone else.

At that moment high score was Ken Hughes’ 9. So I couldn't miss a single shot in that station if I wanted to be in the run. In the Payday Challenge there is no second place winner and in the past editions of the Cup, there had never been a tie.

Took the first shot and hit the paddle, but the paddle was so shot up by then that I couldn't see my impact.

Next shot also hit the mark.

On the next (third) shot, I felt the release to be good, but the shot missed.

I was out.

Next shot was also a miss, but I scored the last shot as a point of honour.

By the end of the day, three shooters: Ken Hughes, John Eroh and David Hitchcock were tied with 9 points and so a shootoff was arranged. Tyler decided to make the shootoff an offhand affair,

For half a dozen rounds, they all missed!

I’m sure that in more than one shooter's mind a question arose about the ‘luck factor’ in shooting. Since the public was getting impatient, Tyler decided to turn the screws back a little and allowed them the kneeling position. For two rounds no one connected.

In the end, Ken Hughes took the shot and missed, John Eroh connected to the delight of the audience that had grown somewhat impatient.

BUT then Dave Hitchcock also hit the paddle!, and now the three way tie was STILL a two way tie.

After two more rounds of misses, Tyler gave up and then Kristen decided to ask if the shooters were willing to declare a tie.

They were and, so, the prize was split.

After a little more (OK, a LOT more) BS’ing we agreed on an early dinner and we adjourned.

Nice and rewarding day with friends at the range.

And, again, the Texas Roadhouse didn't disappoint.

FIRST DAY OF FT.- Next morning, we all were ready and raring to go.
The sight-in session had been successful, as it validated all previously collected information, and so I felt good about tackling the course.
Picture
At the shooter's meeting, MD Tyler Patner gives specific instructions like shooting order and timer setup.
After the shooters’ meeting, a minute of silence was called for in memory of 9/11, a gallant and fitting action on such an occasion that was greatly appreciated by all.
Squads were posted and scorecards distributed.

Picture
Tyler seems to be commanding: Go forth and shoot!
I was squadded with Mike Norris and Gavin Lever. Mike is a veteran shooter in the PCP Open Division and a proper gentleman. Gavin is a Junior shooter, shooting his first FT match. Talk about learning to swim by jumping into the deep end!
I will not chronicle the FT shoot target by target, suffice to say that I made some pretty stupid mistakes (like sitting on a reset string or using the wrong aimpoint in my reticle! LOL), and that fishtailing winds of 7 to 13 Mph that can swing for your 6 to your 3 and then back to your 9 in about 3 seconds are no picnic.

This was the most mischevious lane in the Match. A rat at about 40 yards and then what seemed like a bat (but then was noted that it was an albino hornet) upon a mast at the berm. At 55 yards the distance was not the most complex of issues, but the location where it was, away from all means of wind observing and gauging.
Picture
Here is the rat. Do note that the string (white) that resets the albino hornet is "trapped" by the rat (red reset string), so the wind-gauging capability was much diminished.
Picture
And here is the (in)famous albino hornet.
Still, I kept up the spirits and tied with Mike at 40 out of 52 possible points.
Gavin scored a 4, which is about par, even for  experienced shooters on their first FT Match. Gavin and I agreed to meet at the sight-in range after lunch and go over his gun and his shooting form.
I have to say that I think highly of the young man. As pummeled as he was getting by the rifle (a full power Diana 48), the wind, and the course, he didn't give up and showed his mettle.
We went over a few basics, corrected some details and I gave him ‘homework’ to do while I was shooting the Gunslynger.
I had no expectations about that competition. The new guide requires careful cocking and I was matched against one of the quickest shooters in the competition. On top, the MD had decided to change the normal distances and, while the trajectory was known, habits are hard to change. 45 years of shooting silhouette sort of conditions the mind.
Anyway, Keith Waters displayed his usual speed and excellent form, and I was out after my first match.
When I found Gavin again, we went over his work and I calculated his trajectory using PP-Calc.
When I told him to write down the table, he looked at me as if I was ‘loco’ or something and he asked me if I could Email him the table. I felt REAL OLD, LOL!
A lesson in the millennial generation gap! For them, connectivity and data interchange is just a natural, and expected, fact of life.
Guess it is good to interact with youngsters, you learn something new.
The day ended with the customary excellent dinner with all the shooters, the vendors/exhibitors, and the crew, a good opportunity to meet them outside the range and their range duties.
I would like to point out that this year LEAPERS was present as exhibitor, as well as the ‘new’ Diana brand, that now has three importers into the US market (Pyramyd Air, Airguns of Arizona, and UMAREX), also present were Hawke and Predator Int’l. We missed the usual Crosman table.
At dinner I had the chance to get to know better Brad Bonnar, from Hawke, and, maybe, I will look into their ED scopes early next year. What I saw at the range opened more questions than provided any answers, but you cannot really evaluate a scope of FT complexity in 3 minutes. So, we’ll see if we can arrange for a test.
We also missed Josh’s usually colorful speech, ;-) But Val made up for it with brevity and conciseness.
After food and the raffle, we all went home happy and contented, if not too full.
Picture
I'm happy someone took a picture of me shooting on the first day. By the second, those pants were not quite as clean, LOL!
SECOND DAY OF FT.- We got to the range about 7:15, only to find a full house. A little patience yielded an excellent spot. And I found the gun was shooting a lot higher and to the right. But after more than 50 shots the gun was steady and so I decided to keep the new zero, as trajectory had not changed substantially.
Picture
Ray scoring and Nathan shooting.
On Sunday, as befits any World Class Shoot, the top scorers are all squadded together within each Division, and so I was shooting with Nathan Thomas and Ray Apelles. It was Nathan who told me that the previous day had not been kind to them. I was much more intent on performing my best than on the actual scores.
I was decided, and committed, to put my best effort forward.

Picture

Picture
Not a small target, but the elevation made it a difficult shot.
As the day went by, I was very pleased with the rifle’s performance. The wind was less on Sunday, about 5 to 7 Mph, and the ‘Woods’ course was somewhat protected by the trees, but they also created the situation where it is hard to read the wind. Luckily the strings had not been tied down to the ground (as they were in Lisbon), and it was a great help in connecting with the paddles.
Most of the targets were going down and even though I made a few stupid mistakes (as usual), I was on an excellent track.
By the last two lanes I had only dropped 8 points of 40 and I was ‘right chuffed’ about it.
Then disaster struck. Skunked one target and missed the first shot of the second, so I took a faceplate hit to see where I was hitting. The gun seemed to have moved POI to the left, a full ½ mrad.
Tried that on the last lane and skunked it again. 8 points dropped in the last two lanes!
Wow!
“That is something I’ll need to look into in detail before Nationals come around!” I thought to myself.
Still, the performance of the system, up to that point, had been very good and I cannot really complain. What I have discovered since is that I had two problems: one was the new design of the guide, it didn't survive the pounding that I subjected the gun to in the Gunslynger. A new guide has been made in a more traditional way and was tested at Falls Township and will be further tested in the Long Island Championships. The other problem was the scope mounting protocol I use. With ordinary mounts it works well forever. I use plastic tape as interface between scope and rings. It prevents slippage and protects the scope finish. It will also allow a LITTLE bit of compensation to be placed in the rings.
With the ZR Mount that is unnecessary, and as time went by, the tape compressed and the scope started rubbing on the mount's watertable.

I have, since, milled the mount a little more and created a 0.010" clearance between the scope's saddle and the mount's watertable.

The whole system worked well in Falls Township but that, as they say, is another story ;-)
After the shoot, we had lunch and awaited the Gunslynger finals.
It was a pleasure and a privilege to see Rob Seiden and Eric Brewer go ‘mano a mano’, and to witness Greg Sauve shoot it out with Bill Rabbit.
Excellent shooting by any standards.

I had always thought that the Gunslynger should be shot with the same gun that the competitor used for FT, but, given what I found out when I opened my gun, I have changed my mind.
It will imply taking two guns to the PAC, but the stress that spring guns are subjected to when the competition is that fierce, does require a specially built machine.
The Gunslynger event was animated by Rossi Monreale, of American Airgunner. It is always fun to hear and see his shenanigans.
I should also congratulate the American Airgunner crew, they have learned how to film and take meaningful pictures of the event without interfering too much. I am sure their efforts were appreciated by more than one. Thanks Guys!
After the Gunslynger, the FT shootoff’s took place.
Ken Hughes and Tom Holland contested the second place in WFTF PCP, and Rob Seiden with Brian Vanliew shot it out for first place in Open PCP.
Both shootoff's were thrilling to the ‘Connoisseur’, but I have to admit that the Gunslynger has a lot more spectator appeal and TV potential.
Perhaps we should suggest to Pyramyd Air that the FT shootoff's are carried out before the Gunslynger’s finals.

Lots of ideas were discussed for next year and, I am sure, next year’s PAC will be even better, bigger, and more interesting but, it will always keep the core values of FT: Sportsmanship, Camaraderie, and Innovation at the ‘Front and Center’
The awards ceremony was simple, conducted by Tyler in his usual informal manner.
First places of all Divisions were called to receive their cups and to select a prize from the table. Then second places, then thirds.
Then the Gunslynger places and, finally, Tyler closed the shoot by thanking everyone: attendees as well as crew; and he received a heartfelt applause from everyone there.
Picture
Lots of shiny cups! ;-)

​As is customary at the PAC, First places were called according to the raw score.
Greg Sauve placed top of all classes and so he got first dibs at the prize table.

Peg selected a scope for a prize, then turned around and gave the scope to Nathalie, the Junior shooter that was shooting down 55 yard targets with an HW30, just because no one had told her that could not be done, Way to Go Nathalie! May we see you in many more FT shoots.
I have to say here that in a gesture of generosity, Pyramyd Air gave ANOTHER prize to Peg! Thanks Pyramyd Air!

And so, the PAC #3 came to its inevitable close, and while I was sad that it had to be over, I was also glad that I had been able to BE there. Meet with people I usually see once a year, make new acquaintances and see some great shooters in action, hopefully learning something in the process.
Picture
Just a bunch of friends after a weekend of Fun!
Everyone, me included, wishes I could have shot like this in Lisbon, but life has a way of teaching you lessons, and HOW you take those lessons is as important as the lessons themselves.
We learn more from our failures than from our successes, if for nothing else than because they hurt. But that is life and, as my Father used to say: A champion is not a champion because he never falls; he is a champion because if he falls 20 times, he gets up 21.
The PAC gave me a chance to redeem myself, and it reminded me of why I love FT so much and that is more important than any prize.
Thanks Pyramyd Air and thanks to all the shooters that MADE the event.
Picture
Oh! That's me! LOL!
If you have never been to the Pyramyd Air Cup, DO PLAN on making it there next year. Whether it is at Tusco Rifle Range or any other place, I am sure Kristen, Tyler and the rest of the PA crew will put on a show you would be sorry to miss!

Keep well and shoot straight (except when there is wind) !

Converting a spring powered D34 into an N-Tec rifle

9/2/2016

18 Comments

 
First of all, and upon the good advice of the corporate counsel, the disclaimer:

The conversion done here was carried out by a professional gunsmith. No warranties implied, or otherwise are intended in this article. The milling operations carried are sensitive, not devoid of dangers and of a high precision nature.
Do NOT attempt this conversion if you are not completely qualified to do so.
This conversion has NOT been sanctioned by Diana nor by Mayer & Grammelspacher.
This conversion proved safe IN THE GUN that it was performed. We cannot guarantee that all other guns will receive the conversion in the same way.
Please do not ask for measurements or dimensions, Connecticut Custom Airguns cannot provide these data.
All designs and parts' shapes and dimensions are proprietary to Mayer & Grammelspacher and their Diana brand.


UUufff! That was a mouthful!

Anyway, let's start at the beginning:

Many years ago, an Argentinian designer came up with the idea that a piston airgun could be a far simpler device. So he set to work and came up with a peculiar gun where the lever moved the BARREL back. The barrel, in turn, pushed a floating piston that to its rear had a closed cavity that could be pumped up with air, or the air could be let out to reduce the energy stored in the compressed gas.
The lever then pushed forward the barrel and the loading was through a turn-cock arrangement like many old German guns.
That prototype evolved and eventually became a commercial model, BUT, as it sometimes happens in life, a pair of British subjects (we must remember they are not citizens), was also working on what they termed a "superior device". Superior in the sense that it utilized the TRADITIONAL piston airgun architecture with all its moving parts and peculiar triggers. So, in their zeal, they took the Argentinian designer to court and won the case.

I have always suspected strongly of all litigations around "inventions". Lately, the world has adopted the convention that the patent belongs to the FIRST TO PUBLISH, thereby eliminating the need to demonstrate the specific date of the "invention". Again, I dislike this because it plays into the hands of those corporations that have patent lawyers on retainer and whether they work or not, they charge a minimum monthly fee.

More and more we see all patents in our life (and death) owned by large corporations that can then jack up prices as they want (the pharmaceuticals are a perfect example)

Perhaps, coming back to the "gas-ram" invention litigation, the Falklands war was also a determining factor.

Whatever it may be, it is an undisputable fact that the Argentinians already had a "Gas-Ram" rifle in commercial production and being sold in their market when the idea was patented in the UK.

To the victor go the spoils.

Fast forward to the present day and after a little over two decades of exploitation, the patent expired.

And so, all of a sudden gas springs (different from Gas Rams) began cropping up everywhere. From the Crosman's of a few years ago to the Hatsans and Diana's of present day and interest.
DO note that HW made their own Gas Ram model under license of the Brits, whether sold as HW or as Beeman, it is the same gun.

Another thing that has evolved enormously is the science of materials. We now have materials that 25 years ago would have been unthinkable. From Titanium, steel and high strength aluminum alloys to highly complex polymers for seals we have at our disposal in economic terms things that in years past would have costed hundreds, if not thousands, of dollars and would probably have required a National Security clearance to buy.

The improvement in materials and availability of pure, dry gases has changed substantially what the old Gas Ram was.

I still remember about 17 years ago that I gifted a 0.20" cal. RX2 to my good friend Mike Pearson, airgun hunter extraordinaire.
As soon as he received it he took the pump and pumped it up to the max. Then he complained about how hard it was to cock and how inefficient the machine was.
That experience colored my perception of Gas Ram's (and gas springs, by extension) till the present.

I still fix the occasional RX-2 or HW-90, but after this experience I know that the REAL problem is that those designs and specifications are simply obsolete.

I have to admit that I tackled this project with some trepidation. The modifications made to the gun would be non-reversible, so the gun was modified forever. Something that IN GENERAL, I do not like to do. But the thirst for knowledge and the long term route that I have planned needed this first stepping stone and so we took a gun that was worth the effort.

And here comes another fact that should not surprise anyone: If you want an N-Tec gun, BUY an N-Tec gun. Between the cost of the parts, the original gun, and the labour you would end up paying TWICE what the original N-Tec equivalent gun would cost.

The only valid reason to attempt this conversion is if you have a superbly accurate 34 and you want to up the power.

Of course, it could be argued that it would easier to swap barrels, but sometimes the accuracy is also a function of how the stock fits the shooter and so, swapping barrels while expedient, reversible and economically savvy, does not resolve all the issues.

And there are no lessons learned in a purchase.

So, having explained a little of the background, let's get to the technical aspects
Picture
On the TOP, the N-Tec powerplant, at bottom, the traditional steel spring power plant utilizing a Vortek PG-2 kit with a Vortek Black-Ops seal specially designed for these guns.
The first thing that should call our attention is that the N-Tec unit is shorter than the traditional setup. This means that the pre-compression is very short.
This is one of the virtues of the gas springs: they keep a constant pressure on the end of the stroke and do not rebound as much as the steel arrangement of individual coils that we call steel springs. By eliminating the rebound of the piston, the gun is much more efficient, specially on long transfer port models, like the 34.

The second thing that should call our attention is that Diana ships their N-Tec triggers with TWO dumb pins. And the reason is simple: some parts could get out of place and cause severe problems upon assembly.
I have found that the usage of dumb pins, while not a necessity is a desirability because it speeds the process and helps prevent problems.
Some people say that they NEVER use dumb pins in the disassembly of their guns, of course, when queried, they have to admit that sometimes guns don't get assembled at first try, and the some pieces have become damaged when they fell out of place and the gun was assembled like that.
My grandma used to say that "to those that die of their own will, death is but sweet nectar".  Let everyone disassemble their guns in whichever way they like, LOL!

The N-Tec assembly is composed of 4 parts:
The piston
The gas spring
A plastic spacer/washer that fits between the gas spring and the trigger unit
The T-06 trigger unit.

In opposition to the traditional T-06 trigger, the N-Tec T-06 trigger is an "interference" trigger. That is, it grips the base of the piston's skirt and does not allow the piston itself to go forward. There is no claw, no plates, no balls. Just a ramp that, when the sear releases, allows the piston to slip forward, much like an archer's release
While some have complained about the N-Tec T-06 trigger, I found my units to be surprisingly smooth and consistent in their release. A true pleasure to shoot with, like the other T-06 triggers in the Diana lineup.

The piston lacks the stem and has a little longer body:

Picture
But all other dimensions are identical. Seal is the same.
Picture
Lever engagement and spacing are also identical.
Picture
At the bottom of its excursion, the piston aligns well.
Picture
But the point of insertion for the interference sear showed that there was a need for some relief.
Picture
The complete piston travel is also the same.
Picture
The trigger housing, however is wider. And so it needs to be. The forces that this trigger is subject to are greater than the forces exerted by the steel spring one.
An interesting characteristic of all T-06 triggers is that they can be adjusted out of the gun. By pushing forward the lever that is visible in this picture, the trigger is armed and the release can then be set to the user's wants.
Do note that the trigger housing is also longer, so that means relieving the stock inletting, but we'll see that later.
Picture
The receiver being milled.
Picture
Now the trigger can go in (tests performed without the gas spring). But there is something that does not quite allow full insertion, Yup!, the interference sear needs relieving.
Picture
And then the stock gets milled to the proper depth, width and the shelf that the trigger has is also incorporated.
After the rough milling some scraping got rid of all those whiskers and shavings.
Picture
Because the trigger housing is larger, the rear stock screw needed is much shorter.
Picture
Because the piston has a recess where the head of the gas spring goes into, it is important to assemble everything in a "train" in one continuous motion.
Don't forget to lube lightly the gas spring stem in any N-Tec system.
Picture
By the end of the day, nothing belies the fact that the originally sedate 12 ft-lbs carbine is now a 16 ft-lbs powerhouse.

While 16 ft-lbs may not seem much, do consider that it's twice the rifle's weight with the Vortex Crossbow scope installed..

Shot cycle is not harsh. Sudden, yes. Quick and Forceful. Very convincing. It also suprised me that the recoil is straight in line. No jump. Of course the rifle's architecture has something to do with this, and it is one of the reasons I am not in love with the current N-Tec offerings.

Apart from the 33.33% increase in power, the gun is easy to cock, even with the carbine's short barrel.

I cannot judgea accuracy right now. Some fantastic groups (3/8"@ 35 yards) and some not so good (1" at 35 yards). I think we need to let the old girl settle down to her new powerplant.

The N-Tec architecture is interesting even without the Nitrogen piston. Future work will involve doing the conversion in a D48. I do not expect the same level of energy output increase in the short transfer port models as opposed to the long transfer port models, but it will be interesting to see what happens there. Of course, the aim in the long run is to have a short-stroked, gas springed Diana 54, shall we call it the 540? LOL!

The new interference trigger opens a whole new avenue of interesting possibilities, so we will be doing some work there in the future.

The gas springs have come a long way from the old RX-2 / HW-90 technology.
New gas spring guns are smooth to cock and efficient in the use of energy, unlike the older specimens.

Hopefully, one day, Diana will offer a true Gas Ram, where the power output can be regulated by regulating the initial pressure in the gas spring.

Whatever happens, I am glad to have been corrected about my bad impressions of the gas springs.


Keep well and shoot straight!
