My buddy recently purchased a JAC Uzi and we have no idea how to get it running. I'm 95% sure all the parts are there and that it works (it was on consignment at a reputable reseller, so I hope it works). I can post pics in a little bit, but right now I only have a couple questions. First: do you buy new cans of gas or refill the ones it came with? And if you have to buy them where can I get ones that fit? Or if you just refill the cans how do you refill them? Also, there are two fire selectors, one is like the one on a real steal, and the other looks M-4ish and is functional. I'm not sure if the one that is similar to the real steal is just for looks or if it's broken. I've never delt with a classic gun before, so any advice is welcome. We would like to have it up and running before the 25.
