CA36K Fire Selector
 

Hey, small problem. My brand new CA36K doesn't like semi-auto. After a couple attempts to find a 'sweet spot' it can click in and fire on semi, but it's not consistent and sometimes seems to slip out and I have to switch back and forth from full auto to semi many times before it'll start to work again. I've yet to take the gun apart, although I plan to in the near future, hopefully just resassembly will fix it, but is there anything anyone thinks I should be watching out for in particular?
