aranoid: Long story short: I bought a gun, it wouldn't feed worth a crap. The round would always hang up right above the chamber. I tried 8 kinds of ammo with no luck. The mag was functioning properly, and there was no way to adjust anything on the mag to fix the feed angle. I read on a forum dedicated to these kinds of guns that the early ones had feeding problems when used with newer mags (which I think mine has), and that you have to polish the feed ramp if you want to fix it. So, I got out the dremel and got to work. Turns out that I ground too much out of there though. The gun doesn't have any problems chambering a round anymore, but the cases are bulging because there's not enough support and it's really not safe to shoot. I only bought the gun because it looks cool and because I thought it was a good deal, so even if I could find a cheap replacement barrel for it, I probably wouldn't buy it anyway. I bought some jb weld earlier because it says it can be filed, grinded, etc. My plan is to try and fill in a little more of the big crater I made until it seals up good enough not to let any more gas back in my face, but still feed half way reliably. Does anyone know if jb weld is strong enough for this? Is there something else I should try instead? The way I see it, I can't really screw it up any worse than I already have, and I had a bunch of powder spray my face pretty bad yesterday while shooting it, and didn't particularly care for that. (Thankfully I was wearing safety glasses though).
