Hello again, and thanks to everyone for the help on my last thread!
Unfortunately I'm having a new problem...when I load a new magazine and work the bolt, a round chambers like normal, and fires. The empty casing ejects normally, but the bolt doesn't completely chamber the new round. Sometimes the bolt can be pushed closed and sometimes that round just has to be ejected and a new one chambered manually.
Anyone have any ideas? Or questions for more specifics? Thanks again everyone!
