The Griffin MK2 CQB SBR Warhawk Green model is an 11.5-inch .223 Wylde short-barreled rifle finished in a green anodize and set up from the factory to run suppressed (brand part no. MK2CQB223W115WHG-W). Griffin Armament pairs a 416R stainless barrel with a tuned carbine-length gas system, a pinned PRIMO gas block and its AR-SOB Gen 2 suppressor-optimized buffer, so recoil and gas stay manageable with a can on. The Griffin Silencer Mount muzzle device is ready for the company’s quick-attach suppressors, and the SN-ACH Gen 2 charging handle keeps gas off the shooter’s face. It weighs 6 pounds 5 ounces and is 28 inches long with the stock collapsed. The green finish gives a duty-grade CQB rifle a look that stands apart from the usual black.

Frequently Asked Questions

Is the CQB set up to run a suppressor? Yes. Griffin builds it with a tuned carbine gas system, the AR-SOB Gen 2 buffer and a Silencer Mount muzzle device so it is ready for a Griffin can.

What magazine and warranty come with it? One USGI D&H Industries 30-round magazine is included, and Griffin covers the rifle under its Perpetual Lifetime Warranty.
