Griffin Armament MK2 Patrol Features The Griffin Armament MK2 Patrol is built around a fully ambidextrous forged lower receiver with a 60 degree flared magazine well and integrated trigger guard mirroring all control features so the rifle runs equally well for left and right-handed shooters. The 416R stainless steel barrel is chambered in .223 Wylde a hybrid chamber that safely and accurately runs both 5.56 NATO and .223 Remington ammunition. A tuned mid-length gas system paired with a suppressor-optimized buffer keeps the action running smoothly whether the rifle is fired suppressed or unsuppressed. The pinned Griffin PRIMO gas block and Griffin Silencer Mount muzzle device round out a barrel assembly engineered for long service life having been tested to 47 000 rounds with zero baffle strikes in Griffin s own suppressor testing. Finished in Tetra Brown anodizing on the receiver against a black anodized barrel the MK2 Patrol pairs a distinctive two-tone look with genuine anodized durability. The Griffin Low Pro Picatinny rail system provides a stable optics mounting platform while the M-LOK handguard offers ample real estate for lights foregrips and other accessories. A Griffin Extreme Condition Stock and A3 grip round out the ergonomics and the rifle ships complete with one USGI D&H Industries 30-round magazine. Backed by Griffin s perpetual lifetime warranty the MK2 Patrol is built to be a dependable long-term platform for serious shooters.
