This gun is epic. I recieved it from The Mystery Box of Desire and boy am I happy. Right out of the box, the externals are very good. It's full metal, with quality that can be expected from KWA. The ROF on this thing is a beast even without using a LIPO. The magwell is tight enough so that the mags don't rattle around, but still loose enough to easily reload. Even my Magpul P-mags fit. The dissassembly is similiar to the real thing, and the instructions are in English.
-Magwell fits every standard 5.56 mag.
-Will only fit a mini or an m4 handguard specific battery, which isn't included.
-With a high ROF, your ammo won't last very long depending on play style.
