"I was pretty disappointed with this. I received a Black Ops M4, which is about as low end as you can get. The unit didn't work at all. When I took it apart, I found it had a plastic gearbox (with metal gears inside). I couldn't get the gears to turn and also the trigger didn't send power to the motor, even with it disconnected. In addition, the stock was missing the back cover. The hop up / nozzle was a weird nonstandard configuration that didn't work once I replaced the gearbox with a new one.

-Still Tokyo Mauri Compatible
-The motor worked
-Not heavy
-Lower receiver was nice plastic

- Didn't come with any accessories (battery, mag, etc)
- Gearbox was broken and had a plastic housing
- The rails are very wobbly. No sense mounting on optic on it.

I get that this is a pig-in-a-poke, but I was really upset with this purchase. I must have got the worst of the worst. The description said it had a metal gearbox and the one I got was plastic.

"I received the M4 in the first picture. It's a Black Ops Viper EBB(I think it's a viper anyway). It came with a charger and 8.4v battery. It was labeled 'Returned' and it appeared to function perfectly fine. I bought the gun with the intention of using it for parts so I completely disassembled it immediately.
The internals are what you'd expect in a cheap gun, but in my case they were all brand new.
The EBB gearbox shell that came in this gun probably won't fit any receiver that uses a normal V2 gearbox. The fake bolt is attached to a slide on top of the gearbox which makes it much taller than normal gearboxes.
Externally it's all plastic except for the buffer tube, outer barrel and a few other little pieces. The buffer tube/stock fit my other gun which is good because that's a part I really needed in addition to some internals.
I also want to use the outer barrel from this gun on my other receiver with a free float hand guard I have. But I won't know how that will work out until I find an armorer's wrench.

"Purchased on about 9/21/16. Received an Ignite Black Ops Airsoft M4 Electic Blowback Airsoft AEG, which is probably on the lowest end of the quality spectrum while still having a metal gearbox. One or two minor pieces were broken off the receiver but the gun was firing out of the box, though its fps was very poor (probably ~100-200). The grease in the gearbox was pretty bad so I cleaned and reshimmed it. I also replaced the stock O-ring on the piston head with one that was a bit larger and re-greased the piston, cylinder, etc. The gun fired decently after this - nice and quiet (compared to my CYMA metal AK) - but I have yet to confirm its accuracy and exit velocity. It'll probably last a while but isn't useful for much more than a backup gun.

My major disappointment was that I just noticed that this gun was moved from this boneyard listing to a separate boneyard listing for $10 cheaper, so this review really belongs under that item but this was technically the item I purchased... Anyways hopefully you'll get something a bit nicer if you purchase an item from this listing.
