+1 on the G&G combat machine, I've got it and so far I'm pleased with it, I'm yet to use it on a skirmish (going on the 28th)
As I already have a load of batteries, I've modified mine to carry a large lipo in the front
The charging handle, which does nothing BTW on these ones but does on the more expensive ones does rattle so I'll be modifying it either drop the dust cover to get to the hop up or just to stop it rattling
As there easy to modify, I'll be getting a longer barrel and suppressor for outside stuff then just swap barrels for CQB stuff
I promote the G&G cm16 100%
