Government Profile Barrel with Optimized Gas System
The 16-inch government profile barrel constructed from 4150 Chrome Moly Vanadium delivers excellent strength and heat resistance, finished with a durable phosphate coating for corrosion protection and extended service life. The government profile offers enhanced rigidity near the chamber and gas port for improved accuracy and heat dissipation during sustained fire. The 1:8 twist rate stabilizes a wide range of bullet weights, from 55-grain practice rounds to 77-grain match ammunition. The carbine-length gas system with micro low-profile steel gas block (0.750) ensures smooth, consistent cycling while maintaining a clean profile beneath the handguard.
Black Diamond Billet Upper Receiver
Machined from a solid block of USA-made 6061-T6 aluminum, the Black Diamond Series slick side billet upper receiver features a Type III hard coat anodized finish that provides exceptional corrosion resistance and a premium appearance. The slick side design eliminates the forward assist for a streamlined, modern profile while maintaining compatibility with standard AR-15 charging handles and bolt carrier groups. This precision-machined upper delivers tight tolerances and a solid foundation for accuracy-oriented builds.
M-Lok Freefloat Handguard Design
The 15-inch M-Lok handguard eliminates barrel contact for improved accuracy potential while providing a lightweight, modular mounting platform. Crafted from 6061-T6 aluminum, the handguard features M-Lok slots that allow for direct accessory attachment at multiple positions, reducing bulk and maintaining a streamlined profile. The freefloat design enhances thermal management, keeping heat away from the shooter's hand during extended shooting sessions while allowing the barrel to perform at its full potential.
Complete with Flash Hider
The included GI birdcage flash hider with manganese phosphate finish and 1/2x28 threading 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 configuration requirements evolve.
