CMC Triggers
The CMC Triggers AR Barrel in 5.56 NATO is a quality replacement or upgrade barrel built for AR-15 platforms that demand reliability and accuracy. This 10.5-inch carbine-length barrel is constructed from chrome moly vanadium steel and finished with black nitride, delivering a durable setup for shooters building short-barreled uppers, SBR platforms, or compact defensive rigs. Whether you're swapping in a fresh tube for a worn barrel or experimenting with a shorter profile, this CMC offering gives you a proven foundation without the guesswork.
CMC Triggers has built a reputation in the AR community for precision components, and this barrel reflects that focus. The button-rifled construction ensures consistent bore geometry and helps achieve the accuracy you'd expect from a purpose-built carbine. The black nitride finish resists corrosion and wear, making it practical for hunters, competition shooters, and operators who put their rifles to work in real conditions.
At 10.5 inches, this barrel threads into any standard AR-15 upper receiver and pairs cleanly with your existing bolt carrier group, handguard, and gas system. It's a straightforward swap that opens up platform flexibility without breaking your build budget or requiring custom fitting.
