Centurion 12.5" mid (cut down)
$300.00
Out of stock
Limited time cutdown from 16 inches to a 12.5-inch midweight hammer-forged barrel, mid-length, .750 gas journal w/alignment notch for use with our TABBED gas blocks (non-tabbed gas blocks will still work). The muzzle threads and end of the barrel are not phosphated, as these cutdowns were performed after the chroming and finishing process.

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.
- The 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 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. 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.
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.
