MIL-Spec CrMOV, Chrome lined, Lightweight, Carbine Gas Barrel

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

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 for them.  We now use a heavy duty, double coiled spring pin which can be driven in/out in either direction, instead of the old taper pin. 


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.
