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.

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. Made in the USA.

Freefloat Keymod Handguard

The freefloat Keymod handguard provides 6061-T6 aluminum construction with modular Keymod slots for direct accessory mounting. The freefloat design isolates the barrel from external pressure, supporting accuracy.

Carbine-Length Gas System

This upper uses a carbine-length gas system with a stainless gas tube and .750 micro low-profile gas block positioned beneath the handguard. The carbine-length configuration is optimized for the 14.5-inch barrel length.

Compatibility and Assembly

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