The Griffin Armament MK2 9mm 4.5″ SBR is a fully ambidextrous 9mm AR built on a forged 7075-T6 receiver set. The lower is natively sized for Colt-pattern 9mm magazines and comes with one MetalForm magazine in 10, 20 or 32 round capacity.

It runs a 4.5″ 416R stainless HEDP barrel threaded 1/2×36 TPI with a Griffin 3-Lug Silencer Mount Muzzle Device, a Griffin 9mm BCG, the SN-ACH 9 charging handle and a factory-adjusted Griffin 2-stage trigger. The barrel is headspaced .01″ short to reduce bolt slap when suppressed, and the Suppressor Ready (SR) rail accepts cans up to about 1.550″ in diameter. Comes with a Griffin Extreme Condition Stock (ECS).
