Features
Barrel: The 7.5-inch barrel is chambered in 5.56 NATO and features a 1:7 twist rate, supporting effective stabilization across a wide range of projectile weights. A carbine-length gas system promotes reliable cycling in an ultra-compact configuration. The barrel is finished in phosphate to provide corrosion resistance and long-term durability under demanding conditions.
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 enhances surface durability, while the flat-top design allows for easy installation of optics or backup sights. M4 feed ramps aid in consistent and reliable feeding. The assembly is equipped with a 7-inch lightweight free-float M-LOK handguard that reduces overall weight while offering versatile accessory mounting capability and improved heat dissipation.
