The CMC Triggers CMC BBL 5.56 12.5" Gov Gas Blk/Tube barrel is built for shooters who want a compact AR-15 barrel that maintains reliability and consistency. Chambered in 5.56x45mm NATO with a 12.5" government profile, this barrel is designed to balance rigidity and manageable weight while pairing seamlessly with the included low-profile gas block and gas tube.

This configuration is well suited for building a short-barreled rifle or pistol-length AR platform focused on range use, training, and general-purpose shooting where a shorter overall length is preferred. The black finish keeps the look clean and understated while the government profile supports dependable performance over extended strings of fire. Backed by CMC Triggers’ reputation for precision manufacturing and attention to detail, this barrel assembly offers a solid foundation for your next AR build.
