My Precision Firearms Barrel arrived.
My 20" PF Criterion 6.5 Grendel barrel and bolt yesterday. VERY nice looking barrel. Polished which I didn't expect. Clearly test fired, no burr at the gas port, chamber nicely done and polished.
I pushed a factory AMAX and ELD round into the chamber and they came out with no drama. I also tried some 123 gr AMAX and Nosler CC handloads that were loaded to 2.260" had no problems with them.
So I screwed the barrel into an Aero Precision M4E1 enhanced upper. No problems ejecting live rounds out of the chamber. I took her out today. Initially I had some functioning issues, specifically failure to go into battery. I guessed the extractor was too tight and removed the o-ring from the extractor spring. No issues after that.
It shot pretty good. I wasn't trying too hard, being more concerned about functioning. First 3 rounds through it were at .644". Last 2 groups were .536" and .732" with the Nosler 123gr CC and 31.2 gr of CFE-223. I fired a total or 29 rounds, cleaned the barrel several times and saw no sign of copper fouling.
So far I'm very satisfied.
