Black Nitride Barrel Treatment

The black nitride finish penetrates the surface of the barrel steel, providing exceptional corrosion and wear resistance that surpasses traditional coatings. This treatment increases surface hardness while reducing friction, which contributes to easier cleaning and extended barrel life. The government profile balances weight with rigidity, making this barrel well suited for general purpose applications.

Slick Sided Upper Design

The 6061-T6 billet aluminum upper receiver features a slick sided profile without a forward assist, reducing weight and creating clean lines. The anodized finish enhances surface hardness and provides additional protection against environmental wear. This upper receiver is compatible with standard AR-15 components and offers a solid foundation for this build.

Gauntlet Arms FDE Brace

The Gauntlet Arms FDE Brace is designed to improve shooter control and stability in a pistol configuration. This brace provides a secure interface for shouldering and helps manage recoil impulses. The flat dark earth color matches the handguard for a cohesive appearance while the adjustable design accommodates different shooting positions and user preferences.
