Noveske Commando Barrel Features The Noveske Commando Barrel is machined from 416R stainless steel and cut with a 1:7 twist rate a combination built to stabilize a wide range of 5.56 NATO bullet weights from light varmint loads to heavier longer projectiles. Noveske hand polishes its proprietary Match chamber on every barrel a process intended to improve chambering consistency and support tighter accuracy than a standard mass-produced chamber. Feed ramps are also hand polished smoothing the path cartridges travel from the magazine into the chamber for more reliable cycling. A 60-degree target crown finishes the muzzle end protecting the rifling from damage while supporting consistent bullet exit. A pinned low-profile gas block is set up for a mid-length gas system a configuration that tends to run softer and more reliably than shorter gas systems at this barrel length. The barrel uses an M4-style extension with extended feed ramps for compatibility with standard AR-15 bolt carrier groups. A 1/2x28 threaded muzzle accepts a compensator flash hider or suppressor giving builders flexibility in how they finish the rifle. Each Noveske Commando Barrel is individually serialized and ships with a gas tube matched specifically to its gas system length for sale at GrabAGun.
