Does anyone know how to disassemble/reassemble the 250Z magazines? My magazines are binding the bolt and it looks like the exit hole may need to be honed out a few thousandths to function. Right now I can't load and fire my rifle using the magazines. The bolts binds up at around 3/8" shy of fully closing. Just got it today and the online manual I found doesn't show any disassembly schematics even though they supplied a bunch of different O-rings. I haven't removed barreled action from stock yet and also wondering how to pull bolt out of receiver. I have asked Barra for help and waiting to see if they respond. No help calling their phone number, no one answers or calls back.
