First review for me so here goes.
From previous experience with chinese guns, I have in fact been quite satisfied. Previous to this gun, I have a Galaxy MP5 PDW. It still works fine but I wanted one with a metal body as I want a top mount of a forward ris mount that wont wobble or break off the plastic body of the galaxy. It still runs around 300fps with .2's and is around 5 years old with no upgrades. I still use it occasionally... well less so now I've got this CYMA beauty.
Bought this gun only a week ago but already skirmished with it twice putting around 3000 rounds through it.
