Griffin Armament MK1 Patrol Carbine 5.56 NATO 14.5" 30rd Black

The Griffin Armament MK1 Patrol Carbine delivers precision engineering in a compact 14.5-inch platform optimized for tactical applications. This 5.56x45mm NATO carbine features Griffin's proprietary manufacturing standards and components designed for professional use.

What Makes This Different

Built on Griffin Armament's proven manufacturing foundation, the MK1 Patrol incorporates a mid-length gas system that reduces felt recoil and extends component life compared to carbine-length alternatives. The 14.5-inch barrel provides optimal velocity retention while maintaining maneuverability in confined spaces. Griffin's quality control processes ensure consistent performance across temperature ranges from -40°F to 140°F.
