Recently bought a aac micro 7 in 300 blk for shooting suppressed subs with my oldest kid. He is 8 and a little noise shy right now. Guy told me when I bought it he put 20 rounds through it and it would not reliably extract rounds with 3 brands of new ammo he tried. At least he was honest about it I guess. . I put Hornady black 208 Amax through it and it won’t reliably extract rounds. It also will not eject even when it does extract from the chamber. I don’t see any obvious defects being made to the brass. The bolt is easy to close and open and doesn’t stick the ejector plunger is tight to push in but does move freely. What would you guys do to start resolving this. replace extractor? I obviously should clean out the ejector and make sure no brass in there or crud. Open to suggestions other than send to Remington. Would send to Fosnaugh or other competent Smith way before sending to Remington
Greatly appreciate any help
