Chrome Lined, and top notch quality like you would expect from Centurion Arms are a few reasons why this would be a great option for your next build.
Light Weight Chrome Moly Vanadium. Carbine Length, .750 Gas Block Journal, and a .064 Gas Port.
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. Centurion Arms has their chrome lining applied to twice the thickness of standard small arms barrels.
Centurion Arms uses a 1/7 (1 turn in 7 inches) twist rate in all their barrels. 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 shooter to get the best performance out of this weapon system.
Centurion Arms uses a true 5.56 chamber in their barrels, allowing the shooter the ability to use the higher pressure military ammunition on the market, and helping to enhance reliability.
Centurion barrels are supplied with extended M4 style feed ramps to enhance overall feeding and weapons reliability.
The barrel finish they 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.
