I got myCiener conversion over the weekend but am having a small problem.  My upper and lower fit pretty tight as it is and when I put in the conversion it's a fight to get it back together.  After I do the bolt seems to be getting stuck.  If I put the mag well on my knee and putt a little pressure on both end of the rifle the bolt will slam home.  I was thinking of getting a wedge to put in and see if that fixes it.  Am I on a good track or does anyone have a differnt idea?
