Also, be advised that a KWA lower receiver has a type of "mounting" at the lower back in which the mech box locks into place. If you attempt to install any other brand of mech box, you will have to dremel the crap out of the box (lower back) in order to get proper fitment.
So going with a KWA box (for a KWA AEG) is always a good idea.
