This rifle has an A2 Flash Hider to reduce muzzle flash and a mid-length gas system, that is combined with a low-profile gas block, which provides reliability under any condition.The free-floating Stag 13.5 M-LOK Handguard features a slim, lightweight profile that offers increased ergonomics, maximum airflow, and modularity while continuing to provide the utmost strength and durability. The handguard also provides an uninterrupted picatinny rail along the top which allows room for sights, optics and accessories the shooter may require. The rifle is completed with a Magpul MOE SL Stock, MOE Pistol Grip, MOE Enhanced trigger guard and PMAG. Lowers stamped to reflect our new Wyoming Operations.
