A balanced mid-length General Purpose piston Rifle - This 16" barreled 5.56 NATO chambered GPR is anything but your basic 16" rifle. Smooth shooting piston reliability with the accuracy of a quality DI gun. 

The patented Hybrid Short-stroke operation of the Perun relocates the piston chamber from over the barrel to the top of the barrel nut in the rifle's body. This eliminates additional torque and weight to the front of the gun, which improves accuracy, balance, and recoil management. The Perun utilizes minimal proprietary parts, allowing unlimited customization and modification of the firearm with standard AR parts for the mission. 

The Perun X16-16-GPR-E comes equipped with the proven heavy-duty 4150 Melonited Chrome-Moly Vanadium steel with a 1:7 twist and mid-length gas system. The muzzle is tipped with a 360-degree recoil reducer in black. Superlative Arms provides the Bleed-off adjustable gas block to optimize the Perun to your favorite ammunition and shooting preference. 

With the lower front-end weight, no gas blowback, and elevated sight rails, this GPR still embodies the 'Scoot N Shoot' with the addition of softer recoil and a true floating barrel over typical piston systems. The feather- weight polymer lower is equipped with an NP3 coated two-stage enhanced combat trigger.
The stock for the Perun X16-GPR-E is an ACR style folding adjustable stock. This allows the rifle to be packed and transported easily or shot while folded, if necessary. An M1913 Picatinny rail stock adapter and a 30- round smoked polymer magazine are included.
