Okay guys quick question. I have a Grendel but this question is for my ar-15. So I noticed the bolt was sticking back and couldn't figure out why I cleaned it lubed it really good. I pushed out the rear take down pin about 1/4 of the way and it slammed forward I shot it like this and it cycled perfect pushed the rear take down pin back in and did the same thing? I have never seen this it seems like its binding on something.
