Description
Features
Barrel: The 16-inch M4-profile barrel is chambered in 5.56 NATO with a 1:7 twist rate, supporting a wide range of projectile weights. A carbine-length gas system provides reliable cycling and balanced recoil characteristics. The barrel is treated with a nitride finish to enhance durability, corrosion resistance, and overall service life. The assembly is fitted with a MOE SL handguard that offers a slim profile, improved rigidity, and effective heat management, along with M-LOK compatibility for accessory mounting. The OD Green color provides a distinct visual profile without affecting performance.
Upper: The upper receiver is forged from 7075-T6 aluminum and machined to mil-spec dimensions for proper fit and function. A hardcoat anodized finish protects against wear, while a flat-top configuration allows for easy mounting of optics or backup sights. M4 feed ramps aid in consistent feeding.
