For those AR15 experts out there, please help me out here. I understand is a good idea to use a fresh ejector retaining roll pin. I ordered one from Sinclairs International (along w/other stuff), and see that it is .390" long. The one that came out of the Young Manufacturing National Match chrome bolt assembly is .440". Is this a problem, or do I need to find one that really is .440"?
