The Noveske OG Barrel (brand part no. 07000574) is a 12.5-inch 6mm ARC AR barrel machined from 416R stainless steel, built for shooters chasing match-grade accuracy from a compact gas gun. Noveske Rifleworks cuts its Disruptive Deep Fluting (DDF) into the profile to shed weight and add cooling surface, hand-polishes the Match chamber and extended feed ramps, and pins a low-profile gas block at the port. The muzzle is threaded 5/8×24 for brakes and suppressor mounts, each barrel is individually serialized, and a headspaced, DLC-coated 6mm ARC bolt plus a gas tube matched to the gas system come in the box. Among rifle barrels, this OG DDF favors builders who want a turnkey precision 6mm ARC upper conversion.

Frequently Asked Questions

Does this barrel come with a bolt? Yes, a headspaced, DLC-coated 6mm ARC bolt and a gas tube matched to the gas system are included.

Can I put a 12.5-inch barrel on my rifle? The barrel itself is unregulated, but installing a sub-16-inch barrel on a rifle creates an NFA short-barreled rifle — use it on a pistol build or complete an approved ATF Form 1 first.

What muzzle devices fit? Any 5/8×24-threaded brake, flash hider, or suppressor mount.
