Midweight Hammer Forged Barrel, Midlength, .750 Gas Journal w/alignment notch for use with our TABBED gas blocks (non-tabbed gas blocks will still work.)

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. 



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. Our hammer forged barrels are the best choice for shorter range, combat shooting style and high round counts.

Midweight profile is .750 under the handguard and .740 in front of the .750 gas journal.


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.



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.



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.

    Medium CHF barrel

    First of all, thank you Centurion for making something other than a light or government profile barrel! It's really hard to find good companies that make something besides that. Okay onto the main business- the medium profile CHF CL barrel I bought from these guys is fantastic! Wonderfully accurate, chrome lined, well balanced, good 14.5" length, mid length gas, and fit&finish were great. Literally everything I'd ever want in a barrel. I purchased this barrel for duty/SHTF use and for home defense. I could not recommend these guys or this barrel more. Next on my list to purchase will be their mid length 14.5" improved SOCOM profile barrel.

    Had centurion put a fsb on a 14.5” and had an oss flash hider pinned, this thing is super smooth. Running it with an oss 762 can, centurion does everything right! Perfectly gassed! Couldn’t ask for more!!

    Awesome Barrel!

    Centurion Arms products are amazing. You all should be really proud of yourselves.
    I paired the midweight chf 14.5” barrel with the pinned gas block, bolt carrier group, and forged receiver set with a Geissele MK4 rail. This has been my favorite barrel that I’ve ever owned. I have about 2,000 rounds through it so far. It’s extremely accurate, eats whatever I throw at it, hits some distance (I’ve walked it out 800 yards, but typically sub 400 yards), and it runs and cycles flawlessly - in other words, reliable! It definitely won’t be my last Centurion Arms barrel. I highly recommend it!
