Although it’s not on the website yet, AoA has the new, versatile Diana 34 EMS in stock and available now!
So what is the Diana 34 EMS? It’s a new breakbarrel springer. The initials EMS in the name stand for Easy Modular System. The initials EMS in the name stand for Easy Modular System. The Diana 34 EMS series provides a measure of designed-in customization capability that’s unique for a breakbarrel air rifle.
The first products in the EMS system are four combinations of the basic air rifle. There’s wood and synthetic stocks available, both with a choice of .177 and .22 caliber barrels.
Diana afficionados will appreciate the fact that these 34 EMS series guns are a part of the company’s Performance Line. This means that they carry the prized wording “Made In Germany” on the compression tube.
There’s also the expected, classic two-stage T06 trigger assembly. This is adjustable for first stage travel, sear engagement and pull weight through setscrew adjustments.
The Easy Modular System allows for changeable sights and the ability to swap calibers. The base guns feature spring/piston powerplants, but Diana will be offering N_TEC gas ram conversion kits for those owners who prefer that.
So the Diana 34 EMS series is a combination of tried and tested, classic design, coupled with some significant improvements. They’re mixed with a new level of customisability for a breakbarrel air rifle.
New to the Diana 34 EMS is an innovative shim system for counteracting barrel droop. Not only that, but it can be easily accessed and adjusted by the owner. Under the hood there’s also an improved cocking system, too.
For many years, “barrel droop” has been a problem for breakbarrel air rifle shooters. Now Diana 34 barrel droop issues are a thing of the past with the new Model 34 EMS.
It’s the phenomenon whereby the barrel does not lock-up completely parallel and true with the compression tube. This can be “built in” to the gun from new, or it can happen with time, wear and use. And – to be clear – it can happen with break barrel air rifles, whether spring/piston- or gas ram-powered, from ANY manufacturer.
Typically the barrel is mis-aligned downwards. The result is that the gun shoots low. Hence the term barrel droop.
Because a riflescope is mounted on the gun’s compression tube, the issue is particularly pronounced when a scope is used.
So now there’s a simple and easy way to eliminate barrel droop. But it’s only available in the new Diana Model 34 EMS.
Diana plans to make barrel droop tuning kits available for the Model 34 EMS. These will include spacer shims, an instruction manual and tools. Look for it to become available in the fairly near future.
When I tested a Diana 34 EMS in .177 caliber, muzzle velocity peaked at 1,160 FPS with Predator GTO 5.5 Grain alloy pellets. The maximum velocity with lead was the 971 FPS that was achieved with 7.0 Grain RWS Hobby wadcutters.
As is normal with springers, the lightest, fastest pellets tended to give the highest Muzzle Energy results too. This, of course, is exactly the reverse of the power levels achieved by PCPs.
Overall, the results of this Diana 34 EMS test review show that the gun generates a healthy 15 plus Ft/Lbs of Muzzle Energy with the mid-weight domed lead pellets that will be its staple fodder for most owners.
The average trigger pull weight was just 1 Lb 2 Oz for the gun I tested. Yes, that’s right – just 18 Ounces straight out of the box!
In spite of the relatively light weight of 8 Lb 15 Oz, including mounted UTG 3-9 x 40 scope, the recoil was very manageable.
Accuracy was good too, with best performance being obtained with 7.9 Grain and heavier pellets. At 25 Yards, 10.65 Grain H&N Baracuda Match pellets produced a 10-shot group that fitted inside the size of a Dime. That’s great accuracy…
The break in period for the 34 EMS I tested was very short. As with any spring/piston air rifle, there was a little “dieseling” when the gun was first fired. However, this lasted for just 5 or 6 shots.
The muzzle velocity then rapidly settled-down to consistent figures. This is indicative of high quality assembly – not too much oil or grease in the compression tube!
Overall, the Diana 34 EMS is a successful new “take” on the classic, spring/piston air rifle. The easy cocking and soft recoil are benefits that will be appreciated by many shooters. The up-gradable design gives the owner a range of options unavailable with any other current breakbarrel model.
The price? look for it to be well under $400 with wood stock, less still for the synthetic model.
