Hello, I've recently purchased a Cyma CM002. I upgraded its hopup to a Prowin unit and its inner barrel for a 6.03mm. I'm not even going to ask what you guys think of this AEG because I've heard enough about how cheap it is and bla bla bla. I was thinking about swapping it for the Sig Sauer 556 Shorty from King Arms. You need to know that I live in Brazil, where airsoft guns are pretty darn expensive. So I'm going for a cost-benefit approach here. What are your thoughts on this? Should I do it or it's tomayto tomahto? Thank you all in advance, J.
