The Griffin MK1 Patrol Rifle (Griffin Armament part no. MK1PATROLFDEW) is a full-featured, value-packed carbine worthy of use as a primary rifle right out of the box, chambered in .223 Wylde and finished in FDE. Built around a 14.5-inch 416R stainless steel barrel, Griffin has tested this barrel material to 47,000 rounds fully suppressed with zero baffle strikes, retiring the test barrel only due to extension lug wear, not rifling wear. A tuned rifle-length gas system and a suppressor-optimized buffer system keep the rifle cycling soft and reliably whether you’re shooting suppressed or not. Ambidextrous selectors, a Griffin A3 grip, and a suppressor-normalized ambidextrous charging handle round out a genuinely front-line-ready fighting rifle.
