The 16.1-inch stainless barrel is nitrided for corrosion resistance, threaded, and capped with a three-port stainless muzzle brake that doubles as a suppressor-mount interface. A 1:10 RH twist rate is optimized for common 7.62x39 bullet weights, ensuring reliable stabilization.
Griffin’s 15-inch free-float M-LOK handguard offers 270° of attachment slots and short top rail sections, giving ample real estate for lights, lasers, and accessories without adding unwanted weight. The direct-impingement system keeps parts common with standard AR components, simplifying maintenance and upgrades.
The ambidextrous extended-latch charging handle and standard mag release make manipulation straightforward from either shoulder. SAFE/SEMI/AUTO selector markings and a multi-caliber lower receiver add subtle mil-style touches appreciated by enthusiasts.
A Geissele buffer tube hosts the FAB Defense CORE-CP adjustable stock, providing six-position length of pull, an adjustable cheek riser, rubber butt pad, and integral QD sling sockets. The rifle is finished in a durable Type III hard-coat anodize over 7075-T6 aluminum receivers, matched with a rubber-overmold FAB Defense AGR-43S pistol grip for secure control.
