"Well the internals may be reinforced but the gear box shell appears to be the famous APS exploding gear box
(made of cheap pot metal)
Yup, this is the same gearbox that was used in the APS Patriot (maybe other AEG's also)
Read up on some of the reviews left on the Bone Yard APS Patriot
(That's why it was in the Bone Yard)
So if you think you are getting a good deal here, think again.
I bought this knowing that there was a good chance it might be the exploding gear box and I was right.
After 10 rounds, the gear box case literally exploded into pieces. Spring, piston, and all shot out
all over the place so be careful when you test it.
I just cant give it more than one star primarily because the gear box exploded (my second one)
and this can cause serious injury... ware safety glasses all the time.

It wasn't a total loss as the gears, trigger and other internal are new and are good spare parts.
I actually needed a rear wiring set anyway.
The lower receiver is good and solid and it even comes with plastic hopup that looks like its new.

By now Evike should know the APS V2 BlowBack gear box case is defective and remove it or at least
mention something in the features of the listing that it will(may) crack and explode.
