[QUOTE="Darryle, post: 2609446, member: 109917"] Yes, very good points brought up. The standardization of specs across the large frame AR is one thing I wish would happen. Aero is forcing some to up their game, there was a time when some uppers would not work with the Aero M5 lowers. The cost of these is flooding the market with excellent quality lowers and others are altering their uppers and other parts slightly to work fluidly with the M5 lowers. If you didn't disassemble the BCG and thoroughly clean and lube it, I would suggest that now, inspect the bolt bore for wear, there should be obvious "shiny" spots, make sure these spots are concentric inside the bore, also verify that the gas rings are indexed correctly to each other. Worse comes to worst, I have a ToolCraft HP, .062" FP dual ejector complete BCG that I am willing to clean up and loan to you to remove that potential problem or help diagnose. I also have a Carbine H3 large frame buffer I can add to the loan at the same time. Keep us informed, but I think you have received some excellent advice to try out next range trip to see if you can identify the issues. [/QUOTE]
