I have a vintage M305 that I bought on the GN forum that is in great condition and obviously has a low round count. When I got it I immediately changed out the wood stock for a SAGE EBR. Took it to the range and fired it, but the round didn't eject. I disassembled it a few more times and kept having the same problem. I figured it was a problem with the Sage, so I remounted the original and keep having the same problem. The bolt seems to move fine and it is well greased, but the gun won't cycle. So to break it down, I have a bolt action M305, and was wondering if there is anything simple I can do to fix it?
