Group buy bolt wont close

[grendelnubi]

Sorry. The bolt is the problem. I think its the extractor sticking out into bore too far and wont go over rim. I am using a standard wt buffer and a Strike flat spring. The switching is a complete bcg that works but also has the group buy bolt in it. I think I’m going to order some new extractor clips or whatever they are called and see if different shape or size. Also now matter what I try it still wont chamber and close from the mag, has to be single rd dropped into chamber and them let the bolt fly.

I had this problem once and it was the wrong extractor. Best I could tell it was an extractor for a 223 / 5.56.
