TypeSaber Posted January 18, 2018 Share Posted January 18, 2018 Hi guys, I have G&G CM18 MOD 1 and I'd like to do external upgrade, mainly the Upper and lower receivers and probably rail system too. I know I can probably just save up and get a better gun but it has performed fantastically for me, however, the feel of the plastic on the CM18 feels abit iffy in my opinion. I'd like to know the compatibility of the G&G V2 Gearbox with different metal receivers and the best place to get them! Any help would be appreciate. Thanks in advance!

The saying: "if it ain't broke don't try to fix it" - comes to mind YES you can swap stuff around G&G is quite compatible BUT some receiver threads for rail system "can" be a bit picky ALSO pretty sure you need a tool to remove the CM18 rail system... To fit on the bastid funny ring piece in center: Then it is tear down to replace the bits over AND hope for the best no issues TBH £150 gun, if it works then leave it as is G&G polymer receivers are perhaps one of the best out there They flex a little which is GOOD especially in cold weather stiff brittle hard plastic will break easily if you run into a tree/wall drop it The receiver on G&G CM Range starters are pretty good OK - maybe they could have dropped the big white CM logo but if it bothers ya magic marker I certainly wouldn't recommend you rip a good gun apart just to swap receiver to metal one BUT - it is your gun so if you still want to then go for it personally save £50 or so to put towards another gun perhaps is my view Link to comment Share on other sites More sharing options...
Supporters Gepard Posted January 18, 2018 Supporters Share Posted January 18, 2018 The CM16 line has pretty tough plastic. The polymer on mine has been dropped and bashed half a dozen times and hasn't even shown any signs of cracking. It may be more trouble than its worth to be honest, especially if it doesn't bother you, but I'm sure it can be done. I do agree with @Sitting Duck in that you'd be best leaving it as it is, however.

Sako Posted January 18, 2018 Share Posted January 18, 2018 If it works well then best leave it. buying a new gun with all the bits and bobs you want is a more sensible (albeit more expensive) option, BUT it will always leave you with a solid spare in the event a gun isn’t working/broken.

dazzer306 Posted January 25, 2018 Share Posted January 25, 2018 If it's a blow back gearbox it will have to be a G&G one because of the system they use on top on box, I've tried myself, no blow back will be ok Link to comment Share on other sites More sharing options...
