CMC Triggers Barrel Features The CMC Triggers barrel is chambered in 5.56 NATO and built around a proven government profile design striking the balance between durability and manageable weight that AR builders look for in an everyday barrel. The fast 1:7 twist rate is designed to stabilize a wide range of bullet weights including heavier defensive and match-grade projectiles giving the barrel flexibility across different ammunition types. A 16 inch length keeps the completed rifle maneuverable while still extracting solid velocity from the 5.56 NATO cartridge. The barrel is threaded at the muzzle ready to accept a muzzle device for flash reduction recoil management or suppressor use. A Black Nitride finish covers the barrel providing excellent corrosion resistance along with a smooth durable surface that holds up to hard use. CMC Triggers is known for quality machining and attention to detail and this barrel follows that same philosophy with clean consistent manufacturing. The barrel ships complete with a gas block and midlength gas tube saving the builder from sourcing and fitting those components separately. Whether assembling a new rifle from scratch or upgrading an existing build the CMC Triggers barrel delivers the accuracy durability and versatility AR builders need from a dependable government profile 5.56 NATO barrel.
