The barrel is made from Chrome Moly Vanadium steel and has a matte black Manganese Phosphate finish. The bore and chamber are chrome lined to help resist corrosion and heat erosion. The barrel uses button rifling, M4-style feed ramps, and a barrel extension for consistent feeding. Each barrel is high pressure tested and magnetic particle inspected.

The barrel is listed as fitting AR-15 rifles and has a 10.5-inch barrel length. The package is a single barrel.
