CMC Triggers AR-15 Barrel Features The CMC Triggers AR-15 Barrel is chambered in 5.56 NATO and cut with a 1:7 twist rate a fast enough spin to stabilize heavier defensive and match-grade projectiles alongside standard weight bullets. That versatility makes it a practical choice whether the build is headed to the range for practice a training class or a dedicated duty rifle. The government profile keeps the barrel s weight manageable up front without giving up the strength that a hard-use AR platform demands. A 1/2x28 threaded muzzle leaves the end user free to run a compensator flash hider or suppressor mount of their choosing. Machined from steel and finished in black nitride the barrel resists corrosion while offering a smooth durable surface that holds up to repeated range sessions and field use. CMC Triggers is known for clean machining and consistent accuracy potential and this barrel carries that same attention to detail into a bolt-on upgrade. The package arrives complete with a gas block and carbine-length gas tube so builders are not left sourcing extra parts to get the barrel running. That out-of-the-box completeness makes the CMC Triggers AR-15 Barrel a straightforward foundation for a new build or a drop-in upgrade for an existing rifle.
