Can the ksc Usp Compact use green gas?
 

Just like the title says can the KSC Usp Compact use green gas? Does anyone have any experience using green gas on their ksc usp compact? If so has anyone had any problems doing this. Thanks guys

I fired probably 15,000 rounds through one over a period of 2 years using green gas. I had no issues, other than the piston seal dried out when I left it to sit unused for 2 years, but that was remedied with a little silicone oil and a teardown.

i've been using my USPc with green (propane) as well, with no propane related issues, aside from blowing a gasket or a seal or something once (was apparently easily fixed, you'd have to ask Kwokwai how he fixed it). Put a large number of rounds through it (probably close to 8k now), and so long as you lube it, life is happy. Great pistol, though I will admit to having a few issues (triggers being one).

Anyhow, just remember to lube, and I'd recommend getting a metal slide/outer barrel, as well as an upgraded recoil spring to avoid damage to the frame.

I USE MY FULL SIZE ON GREEN GAS. I FOUND THAT IT RUNS BETTER AND HAS MORE MILEAGE THAN ON PROPANE. (sorry, stupid caps lock)
