MIL-Spec CrMOV, Chrome lined, Lightweight, Midlength Gas Barrel
Midlength, .750 Gas Journal w/alignment notch for use with our TABBED gas blocks (non-tabbed gas blocks will still work.)
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.
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.
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.

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.
