14.5" Centurion Arms 5.56 NATO SOCOM Cold Hammer Forged, Chrome-Lined Carbine-Length Barrel (.750 GB)

Add Tabbed Centurion Arms .750 Low Profile Gas Block here

Centurion Arms in-house pinned gas block is a tabbed, ultra-low-profile, pin-only gas block with no need for set screws and has no threaded holes. Centurion Arms now uses a heavy-duty, double-coiled spring pin, which can be driven in/out in either direction, instead of the old taper pin. 

Original Colt SOCOM Barrel Profile

14.5in M4 SOCOM Hammer Forged Barrel, Carbine, .750 Gas Journal w/alignment notch for use with Centurion Arms TABBED gas blocks (non-tabbed gas blocks will still work.)  The 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.

Cold Hammer Forged Barrels

Hammer forging is a process in which a drilled, reamed, and honed blank has the rifling formed into it by placing the barrel blank on a mandrel that has the rifling ground into its outer surface. 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. These barrels have a slight taper to the bore during the hammer forging process to ensure better accuracy.

Chrome-lined chamber and bore

The hard chrome used to coat the chamber and bore is 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. Centurion Arms has chrome lining applied to twice the thickness of standard small arms barrels

Barrel steel

The steel used in Centurion Arms hammer forged barrels was specifically developed as machine gun barrel steel to help increase the barrel life under prolonged rigorous firing schedules.

Twist rate

This barrel uses a 1/7 (1 turn in 7 inches) twist rate. This is the best overall twist rate for this weapons system. The 1/7 twist will stabilize any of the lightweight 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

Features a true 5.56 chamber in the barrel, allowing the operator the ability to use the higher pressure military ammunition on the market and helping to enhance reliability.

M4 Feed ramps

Barrel is supplied with extended M4 style feed ramps to enhance overall feeding and weapon 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 for 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 through 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 Centurion Arms hammer-forged barrels to ensure the highest quality product.

*"Field-ready" implies it's meant to be used, not just looked at. Field Ready barrels feature the exact same 14.5" SOCOM hammer-forged barrel, with minor surface-level marks that occurred during the finishing process and traveling. These markings are strictly cosmetic and do not impact performance, accuracy, or lifespan.
