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

Clean & then burnish the chamber verified w/ a bore scope.

Thanks guys. Unfortunately I do not have a bore scope. waiting on the new extractor from Remington. Hopefully that resolves it. The extractor will barely hold a piece of brass when the bolt is out of the gun. If you try to use a piece of brass that is being held by the extractor to push down on the ejector it doesn’t want to hold it. Spoke with a tech guy at aac and he said they had some extractors that were bad from the word go. the brass has a bur on it at the rim where the extractor tried to grab it. I didn’t notice it the other day for some reason.
If not the extractor what would be the next most likely cause?
Also, anyone have any tricks to getting the extractor out other than needle nose pliers or a curved pick?

Getting it OUT is a piece of cake.. Getting the new one IN w/o screwing it up is quite another.. Best wishes..

OP- Remove the ejector from the bolt nose. Align the snap in extractor into the bolt nose at 2 Oclock( top). Use a delrin rod to push the extractor in place at 430 Oclock.. Re-install the spring/ejector/cross pin.

The first run of those rifles had the problem you describe. Remington did an informal recall. The fix included a new receiver. I have experience with two and they functioned flawlessly when returned.
