I have a used KWA mp7, after using it a few times. I decided a gas primary isnt for me as I play in a colder climate half the time.
works great, comes with 5 non leaking green gas mags (one magazine lost the base plate, so I JB welded the bottom so the spring stays in, still works great) and a c02 magazine that I bush fixed after losing the end cap (call it a freebie.)

shipping is $20 shoot me an offer.
