Product Description
Centurion M4A1 CHF Barrel with FSB and Extended A2 Flash Hider
14.5in M4 SOCOM Hammer Forged Barrel, Carbine, .750 Gas Journal. Profile drops down to .725 past the gas journal, and steps down to .700 right before the muzzle threads, similar to the original Colt SOCOM barrel profile.
Chrome lined chamber and bore
The hard chrome used to coat the chamber and bore are harder than the barrel steel itself. This aids in longevity and also reduces fouling and corrosion often seen in austere field conditions. Chrome also aids in chambering, extraction, and overall reliability of the weapon. Thus, giving the operator a more reliable weapon with less maintenance. We have our chrome lining applied to twice the thickness of standard small arms barrels.
Barrel steel
The steel used in our hammer forged barrels was specifically developed as machine gun barrel steel to help increase the barrel life under prolonged rigorous firing schedules.
Twist rate
We use a 1/7 (1 turn in 7 inches) twist rate in all our 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
We use a true 5.56 chamber in our barrels allowing the operator the ability to use the higher-pressure military ammunition on the market and helping to enhance reliability.
Feed ramps
Our barrels are supplied with extended M4 style feed ramps to enhance overall feeding and weapons reliability.
Finish
The barrel finish we use 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 70,000 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 our hammer forged barrels to ensure the highest quality product.
