Selling this as my G&P M4 is still my favourite so this won’t get used. It’s the older G&G GBB version which actually has the same body as the aeg so the blowback system is in the form of a V2 gearbox. Green gas is in the mags. 

This is obviously used, the grey mag works fine but the desert one is temperamental. Both hold gas well. Bolt locks back on empty, Semi shoots fine and full auto works fine but it does use up the gas on full auto. On the chrono it’s 270fps so with a bit of fettling it could be better in time, if I was keeping it I’d put a quality piston seal in it as they are simple to take apart. Nice little project RIF or cheap way into a GBB rifle.

light on handguard is only thing NOT included.
