The Griffin Armament MK2 Patrol (brand part no. MK2PATROLWHG-W) is a .223 Wylde semi-auto carbine built on Griffin’s fully ambidextrous MK2 lower, machined to sub-mil-spec tolerances for a tighter, more reliable action. Because its 14.5-inch 416R stainless barrel falls under the 16-inch federal minimum, Griffin pins and welds a muzzle device to it at the factory, bringing total barrel length to a legal, non-NFA 16 inches without any paperwork or wait. A tuned mid-length gas system and suppressor-optimized buffer system keep the MK2 Patrol running smoothly suppressed or unsuppressed, backed by a Warhawk Green anodized receiver and full-length Picatinny rail. Built for patrol-length maneuverability with rifle-length legal compliance, it ships with one USGI 30-round magazine.
