Griffin Armament has released the MK2 9mm PCC, the first fully ambidextrous 9mm AR-15 with a forged 7075-T6 Type III Hardcoat Anodized receiver set. The MK2 9mm uses a lower receiver compatible with Colt or Metal Form 10, 20, and 32-round magazines. The lowers are built with a 1/4×28 nylon-tipped tension screw that can be adjusted to end-user upper-lower fitment preference and features the same ambidextrous controls offered in Griffin’s MK2 series of 5.56mm AR-15s.
