5.56 NATO Chambering

5.56 NATO chambering provides compatibility with both 5.56 NATO and .223 Remington ammunition. The 1:7 twist rate stabilizes a wide range of bullet weights including heavier projectiles up to 77 grains.

Gauntlet Arms Stabilizing Brace

The Gauntlet Arms polymer stabilizing brace provides a lightweight platform for AR-15 pistol configurations. The high-strength polymer construction pairs with the included heavy-duty pistol buffer tube, buffer, recoil spring, castle nut, and end plate.

Trinity Force KMX Keymod Handguard

The Trinity Force KMX 12-inch Keymod handguard provides freefloat design with 6061-T6 aluminum construction, Type III hard coat anodized finish, and modular Keymod slots for direct accessory mounting. The freefloat design isolates the barrel from external pressure, supporting accuracy.

QPQ Nitride Bolt Carrier Group

The 5.56x45mm bolt carrier group features QPQ nitride finish over 9310 alloy steel. The nitride treatment provides corrosion resistance and surface hardness while reducing friction.

Compatibility and Assembly

This full build kit is compatible with mil-spec AR-15 lower receivers. All components use standard AR-15 specifications and threading, including the 1/2x28 TPI muzzle threads matching the included A2 birdcage flash hider.

Lower receiver not included. Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
