stark arms/VFC ZEV g-17. It has a UAC bucking installed and a WE recoil spring. Will come with one mag, that I may or may not have messed up trying to make the mag easier to fill. It's ugly, but it still fills fine lol. $80 shipped. NOTE* frame is cracked a little bit. It's highlighted where. But it's being held together by JB weld. Doesn't affect performance at all.
