Sorry to hear 'bout your "noggin' knocker" ejection problem. Has it always ejected them like that or is it a new thing? If this is not normal for that gun, check your extractor VERY close. It may just need cleaning....or may need removal and cleaning, or maybe a spring. Whatever it takes will most likely be cheap. Get some advice from Kimber but keep in mind that removal is very simple and a lot cheaper that boxing that thing up and sending it off. Keep us informed as to the issue. What's happening with your new AR? I haven't been keeping up here on the forum so I may have missed something.
