Upper Receiver and Barrel

This upper arrives fully assembled, with the barrel, gas system, handguard, forward assist, and ejection port door professionally installed and ready for use. The 7075-T6 aluminum upper receiver with an anodized finish and M4 feed ramps forms the core of the assembly. The 16.5-inch medium profile steel barrel features a QPQ nitride finish and a 5.56 NATO chamber. A mid-length stainless steel gas tube and Recoil Technologies micro low-profile .750 gas block provide a well-balanced mid-length gas system for reliable operation. The barrel ships without a muzzle device, leaving the threaded muzzle open and ready for the suppressor or suppressor host of your choice.

Freefloat M-LOK Handguard

The 15-inch freefloat M-LOK handguard surrounds the barrel and gas system with a partial Picatinny top rail for optics and accessory mounting, an integrated handstop for a natural support hand reference, anti-rotation tabs for a secure fit at the upper receiver, and trapezoid lightening cuts that reduce weight while maintaining rigidity. M-LOK slots along the handguard provide ample mounting space for accessories across the full 15-inch length.
