Sorry, I may not have explained well. I'm not referring to the "edge" of the feedramp (on the frame) but the bottom edge of the barrel. The round hangs up on the barrel itself. I do not think the gap, or what I believe you're referring to as the "edge" is large enough. I understand that there should be a space of about 1/32" between the top of the feedramp and the throat of the barrel. What I'm talking about is taking some material off the barrel itself to INCREASE the distance. When the barrel is pushed to the rear, there is virtually no discernable gap between the ramp and barrel. I have researched the procedure to do this and it seems like it would be rather simple and am pretty sure I can handle it. Just wanted some opinions.
