14.5in M4 SOCOM Hammer Forged Barrel, Carbine, .750 Gas Journal w/alignment notch for use with our 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.
The 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 for them. We now use a heavy-duty, double-coiled spring pin, which can be driven in/out in either direction, instead of the old taper pin.
THESE SERVE AS HBAR SERVICE BARRELS. HBAR ENGRAVING AVAILABLE AS AN OPTION
Current and Future Productions have T-Marked Tapered Lug Barrel Extensions
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. Our barrels have a slight taper to the bore during the hammer forging process to ensure better accuracy.
These are in 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 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
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 weapon 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.
*"Field-ready" implies it's meant to be used, not just looked at. Our 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.
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 all our hammer-forged barrels to ensure the highest quality product.

Absolutely Outstanding products Period!! 100% Perfection thank you Centurion Arms I will definitely be a returned customer!! I have worked for a firearms manufacturer as a CNC operator in the past so I do look for flaws in the firearms parts I order and I can say without a doubt the barrel and bcg I ordered are perfect and I cannot wait to take it out to the range!! Btw I just happened to hear about your company through the “School of the American Rifle” that guy is excellent and even he said your products are amazing so I had to find out for myself and I agree!!! Please keep up the good work please don’t slack like other manufacturers do because people work hard to spend money they really don’t have to buy products they hope won’t fail them. God Bless
I’ve shot close to 500 rounds using this barrel on my AR-15. This barrel has impressed me with how accurate, and perfectly gassed it is.
I highly recommend this barrel.
Even tho it’s the same profile as your typical M4A1 barrel that’s used by the army, this barrel is miles ahead in accuracy.
Can't say enough good things about this. Excellent craftsmanship, wonderfully polished feed ramps (optional upgrade), and the addition of the gas block notch made install a breeze. I am extremely happy with my purchase!
Best barrel. It shoots better than me. I Love the profile. Please make more!
Shot about 700-800 rounds so far and no malfunctions. Gas port is big enough, but I use an adjustable gas block with it, so I can't speak to how well it's gassed other than that. Great quality.
