Re: Burping...
It is actually the Rex-R2 I got from Opteron-O3 a few months ago, it is stock as far as I know. It has a delrin bolt and some type of cup-like seal on the striker. It does have a reg and I tried messing with that but it didnt seem to help. I think I am going to completely disassemble and clean everything and make sure it is all lubed up and give it another shot.
