The forged upper and lower receivers are finished with Type III hard-coat anodize under FDE Cerakote, giving this rifle a durable exterior with a unified, modern look. Standard AR-15 controls include a forward assist, shell deflector, manual safety, and an ejection-port dust cover marked '5.56 NATO.'
The 16 in barrel is 4150 CrMoV steel with a black-nitride treatment and a threaded muzzle capped by a multi-step cylindrical flash hider. The mid-length gas system balances performance and shootability, while the free-float 15 in M-LOK handguard provides ample mounting space and stability via anti-rotation tabs.
The flat-top A3 upper with T-marked Picatinny rail makes mounting optics straightforward. A collapsible six-position polymer stock and a Magpul MOE pistol grip (black) complete the furniture, with a 10.5 in length of pull for adaptable fit. The rifle uses STANAG/PMAG pattern magazines with a stated capacity of 30+1.
