The particular DIANA 34 EMS (Easy Modular System). – Buck. 1

A brand new breed of Break-Barrel Piston gun

Back in 2016 (that has already been 5 years ago! ) Once i met Tobias Schmidt for your second time at Pyramyd Air Cup, we began toying around with concepts for the future of DIANA.
During the long hours associated with talks and idea expressing, we developed a regard and friendship that I was glad to be able to say that provides survived the changing situations of life.
In subsequent years, all of us attended several IWA’s plus PAC’s and our lengthy drives to and from those activities were usually spent idea about the products and the markets.
About 2018, whenever we drove from Maryland in order to Ohio together, we began discussing in earnest the actual EMS COULD mean towards the shooters. Before that, it absolutely was mainly a manufacturing simplification system, where the products might be built using common components and only some parts would certainly differentiate the versions.
Through our discussions, Tobias saw the value the fact that system could bring to the marketplace; specifically, the US market which has a long tradition of “home tinkering” and enjoys the freedom not granted in order to citizens of other nations to CREATE our own rifles.
And so the “Easy Production System” became the “Easy Modular System” with a concentrate more towards the user in order to the maker.

Given the particular HUGE opportunity that developing a new platform brought, we all looked at every detail and every corner and cranny of the gun, from the sights to the rear end plate.

And when we were nearly ready to release the first pre-production steps (first one number of 10 rifles, then a number of a 100), to after that go into production at complete pace, CoViD struck.

This particular disease/pandemic has brought different reactions from different countries. MANY have opted to restrict people’s mobility and get in touch with, some have opted to undertake nothing beyond putting the obligation in the citizen’s shoulders. Other people started with a lenient mindset only to go into panic whenever hospitals filled overnight.

However in all aspects, it has been mainly “social distancing” what provides prevailed.

In a production atmosphere, “social distancing” carries a lots of collateral effects.
Things don’t get transferred since fast and as completely because when there is face to face contact.
Things take, a minimum of, twice as long (if not really four times as long).
There are a lot more errors and more problems that might have been solved, but were not, since people are not REALLY working together.

All of our plans to release the entire suite of parts plus accessories simultaneously with the weapons have gone out the particular window. Though SOME components are ALREADY available. And the cause is simple:

EMS builds on to the excellent results of the NTec series by using the NTec piston and trigger block; after which enhancing the architecture from the gun completely.

There are 3 “reviews” of the EMS presently published:

This final review has a video (in German), that is quite easy to understand even if you do not speak German born.

As good as the reviews are usually from a consumer perspective, there exists a LOT more going on and I will attempt to touch on some factors that seem to me to become of importance, yet ignored by reviews in favour of velocity quantities and pellet tests. When there is enough interest, perhaps we are able to post a complete analysis from the differences and the real benefits of the new architecture.

A typical issue in the fora, usually simply by people who are “keyboard shooters” a lot more than the real thing, has been that the components to upgrade the weapons are not yet available, yet that is not completely true, and in your blog entry we will look into a good upgrade that CAN be performed having a part in the current list of extras from DIANA.

From Metal to Gas Spring

As mentioned above, the EMS develops on the success of the NTec rifles (mainly the 340 NTec) by using the NTec piston (that is stemless), as well as the T-06 NTec trigger (different from the T-06 Stemmed piston trigger).

​ But , take a look at get started:

This is a zero. 22″ cal 34 EMS as they come out of the box.
The “Classic” edition of the stock is the one particular currently available. IF you compare this to an old 34 “Classic” you will see that this stock is usually slightly more slender, and that the particular comb is a bit higher
This puts the particular recoil more in line with the center/shoulder point of contact towards the butt plate, and so, the particular shootability of the gun increases because there is less “jump” towards the gun when the piston will be released.
This really is something that has already been identified simply by HAM’s technical reviewer, my good friend Eric Brewer.
The front sight is really a modern unit with dietary fiber optic “pipe”. It is kept in place with the traditional grub screw from the top and also a nut at the front. And NO the particular synthetic cover is NOT the particular holding nut, it is a threaded cover and thread defender of the ½ “-20 UNF thread at the barrel’s snout.
This is the real enthusiast. Steel. It takes a fifteen mm’s slim wrench in order to losen it properly.
The rear sight is an fascinating element.
Along with dual fiber optic plumbing, it is adjustable for each windage and elevation as well as the screws have re-assuring “clicks” that tell you that the anchoring screws will not move on their own, and also allowing to count the particular variation you are incorporating within the LOS.
You may also appreciate here the shell adjustment screw and enthusiast, they both take a five mm’s Allen wrench. Mess is on the left hands side, nut is for the right, and underneath are usually real nord-loc washers. In case your forks are “Too tight” shoot the gun a minimum of 100 shots before determining to losen the agreement. In any case, you do not need to take the particular stock out to adjust the particular breech-block to fork pressure.
Another thing to notice is that all 34 EMS’s are issued with the Serial Number in TWO places: at the fork as you can see through the picture, but also in the barrel or clip, so that people can understand if a gun is maintaining its original barrel delete word.
This is why, the sight picture is very usable. Shooting with both eye open is possible and fairly accurate.
With the places removed, now we can take away the stock and put the weapon in the spring compressor.
To remove the stock you can find two forearm screws along with a trigger guard/block screw. Within the picture above, you can see that this forearm screws are CURVED into the compression tube completing block. Something that is distributed to some of the best airguns in history.
For the savvy player with the dice, this allows some degree of “tuning” because the tension between share and action can be controlled in a solid manner. This may also be done with the “old” 34, but now the degree associated with adjustment is one degree of independence better.
The EMS has a substance cocking linkage, which was very first used in the 350 Magnum, the compound linkage decreases the Peak Cocking Pressure (PCF), AND allows a simpler disassembly/piston extraction for servicing or upgrade purposes.
This is what you find in the underbelly
This is how the addition pops-up
And you basically remove the linkage from the piston. That allows the piston to become removed without having to disassemble the entire linkage from the barrel, since used to be the case with the “old” 34.
This is the T06NTec trigger block. You can obviously see the steel main springtime and the rear guide in the main tube.
The T06Ntec trigger is definitely an interference trigger. Meaning that there exists a ramp that rises plus locks into the slot on the skirt of the piston. Once the trigger is released, the particular ramp “falls” out of the way.
It is an incredibly quick trigger, especially useful for offhand shots.
Once the back dust cover is taken out, and the compressor has taken all of the stress from the closing hooks, the dummy pins could be inserted and the trigger device can be slid back to show the spring,   as well as the rear guide.
Removing the whole spring enables you to access the  front information.
This is what you have to get free from the gun, from still left to right: Front information, spring, rear guide.
The front guide is really a solid piece of steel, plus adds considerable weight towards the piston. Once that guidebook is removed the gun’s power plant is “skewed” towards lighter pellets.
This front instruction can be replaced with an Anti-Bounce unit, but that is a customized project we may talk about inside a future entry.
In the trigger you will find an easy allen headed screw that should be removed.
Here you will see the screw that will act as solid support for the back guide. You can also see within the bottom of the trigger device the “ramp” that hair into the piston slot, whenever that ramp falls, the particular piston flies forward.
Once that screw has gone out, you can then simply screw the particular NTec gas spring to the trigger unit.
I would STRONGLY recommend using Vibra Tite by applying to the line and then letting it dry. AFTER THAT assembling the NTec gasoline spring to the T06NTec result in block.
The “button” at the end of the stem within the gas spring needs to squeeze into this recess in the piston’s head.
And you must ensure that everything is correctly aligned.
When everything is really a go, you simply insert the particular trigger/gas spring assembly, correctly seated into the piston, in to the gun. I STRONGLY recommend making use of shim material to prevent the particular cuts in the mechanisms pipe from scoring/cutting/hurting the piston seal.
If you want to de-burr the particular edges prior to assembly, use the “quintessential” tool associated with rifle-making. It’s called the “riffler file” and these days the diamond versions are certainly not that expensive. Get an appropriate one and learn to use this (rifflers are used by tugging, as opposed to files that are utilized by both pushing and pulling). It will save you a lot of head aches.
Put everything within, pop the cocking addition in its place, put the weapon in the spring compressor, shrink the gas spring, place in the action closing hooks, put the dust cover.
Assemble the share to the gun, taking care in order to glue some flat cleaners to the bottom of the recesses so as to protect the wooden from the star washer nibbling the stock to loss of life.

​ And check.
With the NTec gasoline spring, it takes a measely 30½ lbs of PCF to fully cock the weapon.
Testing various pellets at short variety will give you an idea of which pellets to try at long variety.
The three pellets which are outstanding in this particular instance are the JSB’s 16’s, the particular 14. 3’s and the GTO’s at 11. 75 grs.
The Crosman, FTT’s,   and other pellets simply did not “jive” using this barrel. Perhaps in the future, after the full 500 shots “running in” has been accomplished items may change a little.
While the JSB 16’s socialized better, the GTO’s possibly need more work.
The JSB’s produced 15 ft-lbs, while the GTO’s yielded upwards of 17 ft-lbs
So , for “real-life” (meaning lead) pellets the particular conversion complies with the directory specs, using the GTO’s (which are not bad as a searching pellet out to about forty yards), it easily surpasses the catalog specs.
This gun is now equipped with a fixed enfold that still allows the particular tuning of the muzzle harmonics, so once the user identifies exactly what he wants to perform with the gun, some adjustment is possible to achieve the best precision with the pellet he selects.
While the gun may seem a bit too long, keep in mind that there will be short barrels obtainable in the future.
Within our tests, the length of the barrel or clip is not as crucial to the power delivered to the pellet such as the PCP’s.

The transformation itself took all of twenty minutes to do and I think it really is achievable by anyone that can transform a spring or a piston seal. I do believe that this complies with the “design intent” when we set-out to make a weapon that was easy to be “converted” as to what each shooter wanted.

That pandemic eases and we learn how to live in the “new normal”, I hope that more and more from the planned accessories and fine-tuning elements will become available.
For the time being, I have guaranteed 8 gas springs to get this done conversion, if you are interested, fall me a line through the get in touch with page.

Keep well plus shoot straight!
