New!! POF Puritan 5.56 Barrel

Posted on June 5th, 2015 by ar15news

POF (Patriot Ordnance Factory) has just released their Puritan 5.56 barrels for sale. These barrels are 16.5″ long and feature a  5.56 match chamber, 5R rifling and a 1:8 twist which together are capable of sub-moa accuracy. They also utilize POF’s patented E² dual extraction technology which makes FTE’s virtually a thing of the past. One last feature is a Black Nitride finish adding corrosion resistance to the inside and outside of the barrel. If you’re looking for a barrel for your next build, this would be a great place to look first. Check them out at

POF Puritan 5.56 barrel

The Puritan 5.56 barrel is constructed from mil-spec 4150 chrome vanadium steel and features a 5R rifling profile with 1:8 twist rate. The gas port is set up for a mid-length configuration gas system. We have also installed the Patented E² extraction technology. The E² dual extraction consists of 4 small channels cut into the walls of the chamber, allowing a small amount of gas pressure to flow backwards and push on the shoulders of the spent casing. This small pressure helps “un-seat” the spent case from the chamber while slightly pushing backwards as the extractor is pulling the case rearward. With this feature, the extractor is no longer doing all the work by itself; therefore the life of the extractor and overall reliability of the rifle system is increased. This feature does NOT deform the spent brass. To finish it off, our barrels are nitride heat treated, which greatly increases surface hardness and makes for a beautiful black and corrosion resistant finish.

MSRP is $215.99

These barrels shoot 1 MOA or better when installed in our Puritan series rifle.
