Griffin Armament Mk2 Rifle Patrol 5.56 14.5 Fde

The Griffin Armament Mk2 Rifle Patrol 5.56 14.5 is a purpose-built 5.56 NATO carbine engineered from the ground up for shooters who demand reliability, ambidextrous controls, and suppressor-ready performance. Griffin redesigned the Mk2 platform around a fully ambidextrous lower receiver manufactured using aerospace-grade tolerances, which means every control—safety, charging handle, magazine release, and bolt catch—mirrors on both sides. If you're left-handed, right-handed, or prefer true ambi functionality, this rifle doesn't compromise.

This 14.5-inch carbine runs a 416R stainless steel barrel paired with a tuned mid-length gas system and suppressor-optimized buffer setup. That combination gives you soft, controllable recoil whether you're shooting suppressed or running it dry. The 416R steel is built to last: Griffin's testing shows these barrels sustaining tens of thousands of rounds while maintaining accuracy and rifling integrity. The rifle ships ready for duty with Griffin's proprietary Silencer Mount muzzle device, low-profile gas block, and charging handle designed to work smoothly with suppressors. It also includes an integrated 60-degree flared magazine well, enhanced bolt carrier group, and Griffin's ECS stock—all the tuning most shooters buy separately.

This is a rifle for the serious shooter: hunters running cans, precision riflemen setting up for multiple roles, and operators building a patrol or home-defense setup. Every part is Griffin, from the maritime-spec receiver extension to the low-pro rail system and dimpled takedown pins. It comes with one USGI 30-round magazine and backs the entire rifle with a perpetual lifetime warranty.
