The Arash sniper rifle is a semi-automatic weapon with rotating bolt and gas operated reloading.

[2][4][5] It is fired in a standing position with a forward bipod and the gun resting over the user's shoulder, similar to an RPG.

It is arranged in a bullpup configuration with the trigger assembly forward of the magazine, which is loaded behind the user's back, making reloading awkward.

The recoil of firing a 20 mm round is mitigated by a huge cone-shaped quadruple baffle muzzle brake and the design of the gun which makes it pivot on the operator's shoulder.

The scope appears to use a copy of the Barrett Optical Ranging System (BORS), which calculates atmospheric conditions to determine the rifle's optimal position to take an accurate shot.
