We are proud to offer our 7.5 inch 400 Legend AR-15 Barrel, 4150 CMV and Melonited/Nitrided, 1/16 Twist, Medium Contour Barrel Profile with a Pistol Length Gas System.

Our AR platform barrels are constructed from milspec or better quality materials, and sourced locally within the country. Our barrels are machined using the latest state of the art CNC equipment and quality control processes. Our barrels are drilled, reamed and rifled and then profiled as one entire operation to ensure tight tolerances and less variation. We use the latest equipment for quality control and testing enviroments. Barrels are then sent off for nitriding or chrome lining (if applicable) before the gas port is drilled and extensions installed. Proudly designed and made in the USA. 

NOTE: Do NOT use 5/8-24 muzzle devices designed for the 300BLK or other 30 caliber rounds. You must use a 5/8-24 muzzle device that has the exit hole enlarged to accommodate this round
