The LANTAC 11.5" 300 Blackout Barrel Blk is built for shooters who demand precise machining and consistent performance from their AR-platform builds. Each barrel is carefully chambered and headspaced to a master bolt face, with the barrel extension individually matched to ensure smooth feeding and reliable cycling. The precision gun-drilled, double-reamed, and honed 416R stainless steel blank is finished with progressive 6-groove button rifling to deliver dependable accuracy with supersonic or subsonic 300 Blackout loads.

This 11.5" barrel uses a pistol-length gas system to promote reliable operation, especially when paired with suppressors or lower-pressure ammunition. Extended M4 feed ramps support consistent cartridge presentation, while the threaded muzzle makes it ready for your preferred flash hider or muzzle device. Ideal for compact AR pistols or short-barreled rifle builds focused on range use, training, or general-purpose shooting, this barrel reflects Lantac’s attention to detail and commitment to precision craftsmanship.
