The Griffin MK2 rifle series improves on the features of the MK1 by improving the foundation of the rifle; its lower receiver. The Griffin MK2 fully-ambidextrous lower receiver is manufactured using state-of-the-art aerospace manufacturing techniques to derive sub-mil-spec tolerances and unparalleled quality. Front to back Griffin rifles leave no stone unturned.

All control features are mirrored affording full-ambidextrous functionality, using intellectual property developed by Griffin Armament circa 2013. 

The MK2 PSD 300BLK Suppressed One-Stamp Rifle is a quality shorty. The tuned pistol-length gas system and suppressor optimized buffer system ensure a soft yet reliable gas system suppressed or unsuppressed. The 416R SS barrel provides exceptional accuracy and durability. We ran one of these barrels to 47,000 rounds 100% suppressed while test firing suppressors with zero baffle strikes and the rifling was still present. The barrel was retired due to extension lug wear, not due to barrel rifling wear. Other case studies such as multiple M24 SWS barrels holding 0.35 MOA to 20,000+ rounds in army testing, provides further evidence that 416R SS is an extremely durable barrel material.

Options include furniture color. This rifle handles like an SBR without the need for two tax stamps, and comes with a pin and welded GP7 Suppressor making it a one-stamp suppressed non-NFA 16.1" length rifle. We do not charge for pin & weld service. For questions on ordering or to discuss options contact customer service 1-262-200-0003
