If you have access to dummy rounds, just hand charge those rounds through the gun while you watch tv and do that for a few mag cycles. As you do you should notice less double feeds or snags. If you lives close enough I could crank out a handful of dummy brass rounds for you to work with. Or you can pay out the ass for 10 or 20 snap cap rounds. However that wouldn't be cost efficient, those things are high. Try changing mags or anything different you were doing at the range. Anyway I am sure things will correct themselves after the gun is ran for a while.
