Barrel: The 16-inch barrel is chambered in 5.56 NATO and features a 1:7 twist rate to stabilize a broad range of projectile weights. A mid-length gas system provides a smoother recoil impulse and consistent cycling. The barrel is finished in phosphate to enhance corrosion resistance and long-term durability under hard use. Upper: The upper receiver is forged from 7075-T6 aluminum and machined to mil-spec dimensions to ensure proper fit and function. A hardcoat anodized finish increases surface durability, while the flat-top configuration allows for flexible optic mounting. M4 feed ramps promote reliable feeding performance. The assembly is fitted with a 13.5-inch lightweight free-float M-LOK handguard that reduces forward weight while offering extensive accessory mounting capability and improved heat dissipation. A Magpul MBUS sight set is included, providing a durable polymer back-up iron sight solution that folds flat when not in use. Bolt: This upper includes a full-auto profile bolt carrier group and charging handle. The bolt is manufactured from Carpenter 158 steel and undergoes high pressure testing and magnetic particle inspection to ensure strength and reliability.
