Z is burping

[Bountyman]

Hey all,

played ball yesterday and my gun shot fine, but after i cleaned it and oiled it this morning it has started burping. Every 10-15 shots I'll get a burp sometimes short then others its like in full auto a couple of seconds. At first i thought it was because i was low on CO2 but i put the tank on my other gun and it shot ok.

Any suggestions on what to look for?

hmmm. im gonna answer this with the most common solution given to me: turn your velocity up, and lube your internals.

that is the thing, this started happening after i lubed my internals, maybe i need to replace the o-rings. would an O-ring have something to do with it? And if so, which one generally is it, one on the bolt or vertical feed?, or does it not matter, can a bad o-ring anywhere cause burping?
