Hello, guys. [I know I just posted a thread about my SCAR, but it's a completely different matter] A friend of mine is selling his lightly used ICS CXP UK-1 TransforM4. Do you guys think it's a good deal for me to trade my VFC SCAR-L CQC for that? I like the fact ICS has the quick spring-change feature, but I'm quite unsure if that's worth it. Doesn't its gearbox fail on the long run? I avoid tinkering as much as I can, since parts are expensive as heck here in Brazil. Thus, a reliable and good-performing AEG is a priority. Thanks!
