The Diana 34 EMS series is part of the brand’s premium line of break-barrel springers. This air rifle has been in production now for about 36 years years, but they’re bringing new upgrades to the table. Now, with its Easy Modular System, the Diana 34 EMS series provides enthusiasts with a designed-in customization capability.

This single-shot gun has the ability to swap barrels so the receiver can propel both .177 and .22 caliber pellets. The business end also has interchangeable options, including a tunnel sight, muzzle brake, and fiber optic bead. But the most notable improvement on the rifle has been its two-piece cocking lever “that reduces the effort needed to change the gun,” as Field and Stream noted.

The locker lever is now divided into two parts. First, the inlays are now polymer coated, which makes the process smoother than the old Diana 43.

“A light slap on the 19.4″ (49.5 cm) rifled barrel, then the F variant of the air rifle (7.5-joule version) can be comfortably cocked without much effort.”

When it comes to the front of the barrel, you have the traditional chemical bluing. It’s all steel and is nicely finished to precision. There will be a few polyester bits at the end of the cylinder cap and the open sights. You can choose to have the barrel end without an open sight or upgrade it to a metal front sight and front sight tunnel. It also has an adjusted option if you want to add a silencer to this rifle.

The fiber optics are made of plastic, too, but they’re thick and stable to use. These optics are fully-adjustable as well.

“With dual fiber optic pipes, it is adjustable for both windage and elevation and the screws have re-assuring “clicks” that tell you that the screws will not move on their own, as well as allowing to count the variation you are incorporating in the LOS.”

The EMS on the Diana 34 builds on the success of the previous NTec rifles, specifically the 340 NTec, and that classic T-06 NTec trigger, as noted by Connecticut Custom Airguns. This is adjustable for first-stage travel and sear engagement.

Core Improvements

One of the missing components of the older Diana 34 has been the “barrel droop,” according to Air Guns of Arizona. The barrels were misaligned downwards, so the shots went out lower than the right. This is where it got its name, “barrel droop.”

“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.”

The riflescope used to be mounted on the gun’s compression tube; there’s no way to adjust this. The manufacturer improved this by introducing tuning kits, now available to the Model 34 EMS. The tool kits include an instruction manual, tuning tools, and spacer shims.

This ultimately improves Diana 34 EMS’s experience regarding the said issue.

Shooting the Diana 34 EMS

Multiple reviews already not how seamless this new Diana air rifle is when it comes to shooting tests. One thing to note is Diana’s T-06 trigger makes all the difference. It’s well adjusted, and it fits perfectly. The trigger weight can also be adjusted based on your preferences, so unique customizations on the Diana 34 EMS makes for a more seamless feel.

The recoil is pretty predictable. Reviews note its rate as “medium.”

On average, the air gun generates around 15 ft/lbs of muzzle energy with the “mid-weight domes lead pellets,” according to Air Guns of Arizona. As for the pull weight, it will take you only 1 lb, 2 oz. for the gun.

When it comes to accuracy, it was tested to pair best with heavier pellets like the 7.9 grain. The muzzle velocity is pretty stable too.

You can also test different pellets for short and long ranges.


The Diana 34 EMS is a substantial upgrade to a good ‘ol classic. Because of its wide range of customizations, enthusiasts can customize it based on their preferences. They also included kits that will solve previous issues, making the assembly easier to do.

As for its craftsmanship, its “Made in Germany” mark stays true to its words. Smoother cocking mechanisms, softer recoil, and basic upgradeable design make it one of the best options for EMS to date.
