I finished my 6mm BR build a short while ago. One thing I am not happy with is the way it ejects. Its a single shot. It wants to do what its supposed to do and throw the brass if I work the bolt fast. If I work it slow it stars to eject and about half way out the extractor claw slips off the brass. What can be done? What does a factory single shot do? I have made no modifications to the bolt. Is there something I can do to make it not grab and throw the brass.
