APS Full Metal ASR Competition Style Receiver Set - Black

"Good receiver. Needs modification to fit some gearboxes but it's APS so that's a given

"Pro's:
Solid build quality and great paint finish. All parts came together with little or no hassle.
Standard V2 gearbox seats nicely in lower receiver with almost no fitment issues. Rear wiring was no problem, just smooth any sharp edges where the buffer tube connects.
APS outer barrel and barrel shroud all fits together with the piece perfectly.

Cons:
Not really a con, as I did not read the product description properly. The charging handle will not work with a standard V2 gearbox. This is designed for an electric blowback gearbox. (See product description.) So choose wisely as I made that mistake.
The only issue I had was that the anti-roll pins are fixed with tiny screws and the machining of the screw head is incredibly faint. i.e. a hex or Phillips pattern was barely visible, so I just used my old pin instead. These will strip quickly if you are a tech who likes to open the box a lot.
The mag-well is also machined incredibly tightly and my G&G 120rd midcaps don't fit, but high caps and small p-mag's will fit. But if you are inclined, some light filing will do the trick.

Overall great product and will highly recommend it with a compatible EBB V2 Gearbox.
