Make sure the chamber is clean. Carbines never had a good chamber brush and this area gets neglected during cleaning. I use 9mm bore brushes and a short Chamber Maid rod, a flexible plastic coated steel cable, and clean from the receiver end.
You can also slide your cleaning rod in muzzle first then screw the brush in from receiver and pull it into the chamber to clean.
You know, after thinking about it and everything, this very thought came to me. I'm thinking it could be indicative of the kind of malfs I'm getting. Maybe the chamber needs a good working over. I don't think I've ever done it. I clean with a bore snake mostly. Although in the initial cleaning I think I used a traditional brush with hoppes down the bore. But I don't believe I ever worked on the chamber at all. Hmmmmm..............................

Thank you for the thoughts.

Let me ask this issue another way, you guys that have carbines that run, can you move your mags around a bit when they are seated?
