Description
Add Tabbed Centurion Arms .750 Low Profile Gas Block here
This barrel sports a highly requested mid-length gas system and a .750 Gas Journal w/alignment notch for use with a 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 w/o the M203 flats.
Centurion Arms 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. Centurion Arms now uses a heavy-duty, double-coiled spring pin, which can be driven in/out in either direction, instead of the old taper pin.
Current and Future Productions have T-Marked Tapered Lug Barrel Extensions
These barrel extensions accept both standard bolts as well as new E4 Tapered Bolts. They are NOT compatible with KAC E3 bolts.
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. These barrels have a slight taper to the bore during the hammer forging process to ensure better accuracy.
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. Centurion Arms has chrome lining applied to twice the thickness of standard small arms barrels.
Twist rate
This barrel uses a 1/7 (1 turn in 7 inches) twist rate. 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
Features a true 5.56 chamber in the barrel, allowing the operator the ability to use the higher pressure military ammunition on the market and helping to enhance reliability.
M4 Feed ramps
Barrel is supplied with extended M4 style feed ramps to enhance overall feeding and weapon reliability.
Finish
The barrel finish 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 for maximum protection even under the gas block.
*"Field-ready" implies it's meant to be used, not just looked at. 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.
