Lightweight Hammer Forged Barrel, Carbine, .750 Gas Journal w/alignment notch for use with our TABBED gas blocks (non-tabbed gas blocks will still work.)
If no barrel nut is chosen when ordering a pinned gas block, we will leave the taper pin slightly out for ease of removing to install your barrel nut. Taper pin must be re-installed in the same direction it arrived, and then set fully into place.
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.
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.
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.
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.
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(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.

Its a Centurion barrel do I really need to explain ? If you know you know , go on & purchase with confidence
Personally i will be purchasing nothing but centurion arms barrels from here out. Customer support is fast and very helpfull. Probably the best price you’ll find for a chf barrel too. The Leclairs are good people making good products, support those who support you.
Awesome barrel! Itâ€™s extremely soft shooting and very accurate. 10/10 would buy again.
I bought this barrel for a SBR project. This barrel, combined with a good 1-6 and good quality M193 ammo, fast first round hits were a breeze even out to 300+ yards. With mil spec and match ammo, this barrel shoots lights out, with proper function and pressures. I've recommended this barrel to friends as well, it's just that good.
