Centurion Arms 11.5” 5.56 CHF Lightweight Barrel - Carbine Gas
The Centurion Arms 11.5” CHF barrel features a Tapered and Chrome Lined Chamber and Bore, 1:7 Twist Rate, Lightweight Profile True 5.56 Chamber, M4 Feed Ramps and a Carbine Length Gas System.
Some of the most accurate, well gassed, and durable barrels out of the box for your AR Platform Rifle. The Centurion Hammer Forged Series of barrels are designed to withstand very high round count shooting whilst maintaining excellent accuracy. Centurion barrels also feature a very intuitive notch behind the gas block, which mates with their notched gas block ensuring proper alignment during installation and use. (Any standard un-notched gas block will also work)
Cold Hammer Forged
Centurion Arms Cold Hammer Forged Barrels are made by a drilled, reamed and honed blank on a mandrel hammered by two opposing hammers to form the rifling. The result of this process is an extremely smooth and consistent surface which creates a more accurate barrel. The barrel also ends up with a slight taper to the bore that aids in accuracy. During the forging process the barrel steel is hardened creating a much longer lasting barrel, making it a great option for those who tend to shoot higher round counts or at a faster rate often.
Centurion Barrels are made from a specifically developed machine gun barrel steel that helps to increase the barrel life under prolonged rigorous firing schedules
Chrome Lined Chamber and Bore
Centurion barrels feature a Chrome Lined Chamber and Bore. The Chrome used in this process is harder than the barrel steel itself and aids in barrel longevity and resistance to fouling and corrosion in austere field conditions. Centurion Arms applies their chrome lining nearly twice as thick as most standard small arms barrels. The Chrome lining also aids in chambering, extraction and overall reliability of the weapon
Centurion Barrels use a true 5.56 chamber which allows the end user to reliably use multiple types of ammunition along with high pressure military ammunition
Centurion barrels are all HPT (High Pressure Tested) where a proof load rated at 70,000 PSI (much higher than a normal round) is fired through the barrel, and then the barrel is MPI (Magnetic Particle Inspected) to detect any flaws in the barrel steel from the proof load.
Centurion Barrels include extended M4 Style feedramps to improve feeding and reliability
The barrels are manganese phosphate coated on the exterior. The entire barrel is finished before a gas block is mounted to ensure the entire surface is protected, even under the gas block. This allows for better absorption of oils to prevent corrosion.
