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.”
