Bolt carrier is clean, Ive been using Rio's for over a year and have been extreamly reliable, but I did just pick up a new case. So I will try to run some different ammo through and see if I get the same result. I will check for trash under the extractor....thanks for the advice!
P.S Wish I could make the 3gun this weekend Frank.....too much night work this week and need to get work done around the house and garden!
