Overview
Built for shooters who want a straightforward, ready-to-run rifle, this model pairs a 16" 5.56 NATO barrel with a carbine-length gas system and an optic-ready A3 flattop upper. The 15" M-LOK handguard provides ample space for accessories, while the Magpul MOE grip and included 30-round PMAG give it a practical out-of-the-box setup. Forged 7075 T-6 aluminum upper and lower receivers, along with a standard mil-spec trigger and A2 flash hider, keep the package grounded in familiar AR-15 configuration. It suits range use, training, and general-purpose shooting where modularity and a complete factory build matter.
