Double Bell, like most Chinese brands, are renowned for shamelessly ripping off other IPs. Fact. But when the Marui PChan is $800, this seemed a decent compromise for a purely showpiece gun. What I wasn't expecting was genuinely good build quality (and 420fps out the box, requiring down-tuning!). I bought 3 extra mags and in full day's playing, I only had 3 stoppages, that were all fixed with a mag dump and reload. The gun is exceptional. It's more accurate than it should be, sounds aggressive and doesn't 'creak' the way I expected it to. For a knock-off, it's very well built and well worth the $90 I paid for it - but I could have paid double that and still felt like I got a good deal. It seems that plagiarism has made these companies so rich that they're now using better materials and have a better QC process. Terrible for commerce but great for a softy on a budget. It only loses a star for ethical reasons.
