Gauntlet Arms Stabilizing Brace

The Gauntlet Arms polymer stabilizing brace provides structural integrity for stabilization. The brace is paired with a complete buffer system including pistol buffer tube, buffer, recoil spring, and necessary hardware.

Compact 338 ARC Configuration

The 10.5 inch HBAR profile barrel is chambered in 338 ARC with a 1 in 8 twist rate for projectile stabilization. The phosphate finish offers corrosion resistance and surface hardness. The pistol gas system is matched to the barrel length for reliable cycling. The 0.750 inch gas block provides consistent operation. The birdcage flash hider reduces muzzle flash.

M-Lok Freefloat Handguard

The 10 inch handguard features M-Lok attachment slots for modular accessory placement. The freefloat design isolates the barrel from handguard contact. The handguard maintains a lightweight profile while allowing for accessory customization. The nitride finished bolt carrier group provides enhanced corrosion resistance and reduced friction.
