I just got this gun about 2 hours ago. Now i bought a Xcortech Chrono a while back to measure the performance of my team's guns. I installed an Intellect 9.6v Nunchuck 1600mah battery into the hanguard (which even if you have excess wiring, it will still fit nicely) and loaded the magazine. The mag winds very smoothly and it has NO wobble at all in the magwell. I fired semi auto and got these readings: 379.6, 384.2, 387.0, 376.8, and 385.1. So basically they do advertise the FPS correctly. It's gear cycles sound and feel smooth and powerful, and the rate of fire with the 9.6v is very nice as well. Body is made of plastic but it's very tough and durable, so BB's ain't gonna get through it any time soon. Folding stock is tough as well and the catch is made of metal i think, can't be certain. The Iron Sights are aligned accurately, and wont get in the way of a holosight. A foregrip is kind of impractical because of it's distance from the magwell. But to each is own. Overall a must have, but i do have couple peeves: The optional MK36 Magwell adapter for M16/4 mags, WILL NOT FIT because there is interference with the body of the gearbox. So think before you buy. And last is the magazine size; it is a near impossible fit to certain M4/16 mag pouches, so if using the mags as bandolier style (stacked) just be sure to make your shots find their target or 470 rounds will be gone in no time.
Solid body (will endure massive impacts from enemy weaponry).
LI-PO ready system.
Excess battery wiring is not an issue as room is highly available.
Wobbleless magazine with a smooth winding cycle.
Folding stock for the "in your face" routine.
Near perfectly aligned sights.
Will not accept the MK36 M16/M4 Mag Adapter.
Mags are too big to fit into certain M16/M4 pouches (recommend MOLLE M16 pouches either mounted to a vest or securely to a belt rig).
