Precision Barrel with Optimized Gas System
The 16-inch barrel features an M4 contour profile that delivers the ideal balance between rigidity and maneuverability, finished with a durable phosphate coating for corrosion protection and extended service life. The 1:8 twist rate stabilizes a wide range of bullet weights, from lightweight 55-grain plinking rounds to heavier 77-grain match ammunition. The carbine-length gas system with micro low-profile steel gas block (0.750) ensures smooth, consistent cycling while keeping the profile slim beneath the handguard.
Freefloat M-Lok Handguard Design
The aluminum freefloat M-Lok handguard eliminates barrel contact for improved accuracy potential while providing a lightweight, modular mounting platform. The M-Lok slots allow for direct attachment of accessories at multiple positions, reducing bulk and maintaining a streamlined profile. The freefloat design also enhances thermal management, keeping heat away from the shooter's hand during extended shooting sessions.
Precision-Machined Upper Receiver
Machined from 7075-T6 aluminum and treated with a hard anodized finish, the stripped upper receiver features M4 feed ramps for reliable feeding with a wide variety of ammunition profiles. The anodized surface provides excellent corrosion resistance and a durable foundation for your custom build. This upper receiver accepts standard AR-15 charging handles and bolt carrier groups.
Complete with Flash Hider
The included GI birdcage flash hider threaded 1/2x28 effectively reduces muzzle flash while protecting barrel threads when not using alternative muzzle devices. This standard A2-style flash hider provides proven performance and can be easily replaced with suppressors or muzzle brakes as your needs evolve.
