MIL-Spec CrMOV, Chrome lined, 14.5" M4 Enhanced SOCOM Barrel

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


Similar to the original Colt SOCOM barrel profile, but in the highly requested  midlength gas system and no M203 flats.

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.

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.

Weight  2lbs  .5oz

Gas Port  .075"


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.

*****Centurion Arms barrels require no further break in*****

*** We recommend gunsmith installation for all of our parts. We cannot warranty items damaged by improper installation.

    Great Barrel!!

    It may not be CHF, but this barrel is solid performer, the accuracy of it is awesome. I really like the pinned lo-pro gas block, it's very well done. I will purchase another one of these barrels for a future project.

    This barrel is awesome! I've only got about 100 rounds through it so far, but it is printing groups at about 1.5 to 2 inches at 100 meters. I will buy another one of these for an upcoming build/project.

    Great Barrel!!

    I ordered this barrel with the pinned lo-pro gas block. The quality is great and the accuracy is much better than I expected with groups averaging 1-1.5 inches at 100 meters with 55 gr Federal bulk 5.56. I will definitely buy another one of these for a future build.
