KSC USP.45 venting all the time?
23 September, 2012, 03:43
Hey guys,
I've picked up a KSC USP (non-system 7) and it just keeps on venting. Can't get a single shot off. I've cleaned all the mags and valves so I'm pretty sure they're not sticking. Anyone got any rough ideas why it'll vent an entire mags worth of gas on the first trigger pull?
I did wonder if it was the hammer spring or something? If I can't fix it I'll just sell it off cheap. I'm sure I could make my money back on the mags alone?
It's an old KSC, full ABS with the metal loading nozzle, none of this fancy S7/NS2 business

Success!
Turns out the O-ring in the loading nozzle assembly had gone AWOL. I had another KSC USP here for parts and now it's working! Will test it out properly tomorrow!
