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?
