Centurion Arms Barrel Forged Hammer 16in Black NSN 9305.20.9000

Centurion Arms Barrel Forged Hammer 16in Black NSN 9305.20.9000. The blank and mandrel are then placed between two opposing power hammers and the blank is beaten around the mandrel leaving the rifling pattern in the barrel. This process leaves an extremely smooth and consistent surface on the inside of the barrel that lends itself to excellent accuracy. The forging process also work hardens the barrel steel causing a very durable and much longer lasting barrel. Centurion Arms barrels have a slight taper to the bore during the hammer forging process to ensure better accuracy. Specifications for Centurion Arms Barrel Forged Hammer: Manufacturer: Centurion Arms Color: Black Finish: Manganese Phosphate Barrel Length: 16 in Barrel Profile: Government Gas System Length: Mid Length Barrel Twist Rate: 1-7 Gun Model: AR-15 Weight: 1.64 oz Features of Centurion Arms Hammer Forged Barrel Barrel steel - The steel used in hammer forged barrels was specifically developed as machine gun barrel steel to help increase the barrel life under prolonged rigorous firing schedules. Twist rate - Centurion Arms use a 1/7 (1 turn in 7 inches) twist rate in all barrels. This is the best overall twist rate for this weapons system. The 1/7 twist will stabilize any of the light weight 5.56 bullets as well as any other twist. This twist will also stabilize the newer heavier bullets that are being used allowing the operator to get the best performance out of this weapon system. Chamber - Centurion Arms use a true 5.56 chamber in barrels allowing the operator the ability to use the higher pressure military ammunition on the market and helping to enhance reliability. Feed ramps - Barrels are supplied with extended M4 style feed ramps to enhance overall feeding and weapons reliability. Finish - The barrel finish is a manganese phosphate finish (Mil-Spec A-A-59267). This finish allows for better absorption of oils to help prevent corrosion. These barrels are all finished prior to any gas blocks being mounted to ensure the entire surface is covered to maximum protection even under the gas block. HPT/MP inspected - HPT(high pressure test) is a process where a proof load rated at 70000 psi far exceeding a normal round is fired trough the barrel then the barrel is MPI (Magnetic Particle Inspected) to detect any flaws in the barrel steel from the proof load. These are standard quality assurance tests performed on all Centurion Arms hammer forged barrels to ensure the highest quality product.
