Just tried out my CMMG mid-length gas 16" AR-15. Put the lower together myself with a JP trigger. Plopped the upper on there after a little bit of lubrication (but I didn't do a whole lot since I'm new to these rifles). I was shooting some American Eagle Tactical XM193, all I could find locally. Everything was fine for 20-30 rounds until I got a failure to fire. Extracted it and didn't notice a primer strike, then noticed that a little piece of primer flew out with it. Tried a some more rounds and noticed a few primer shards just behind the chamber there between the lugs.
Dangerous? Something wrong with the rifle? Hoping to get it out to the 3-gun match in the morning but it's not looking good at this point.
