My gun was 85 dollars and worked great for a year w/o maintenance. It still works decently, but according to chasey I need to get internal upgrades. The only thing I could find for my gun was a spring upgrade, so I suppose I'll be getting that.
One more question guys, when I remove my barrel and look through it, the opening isn't circular, it looks like a little sliver is filling it in, making it more like an oval (think of the moon a few days before it's full). I turned my hop-up off, and even to full, and that sliver doesn't move. Is that a problem?
