ive been using this gun for a while named the mpx. its 70k. i really like this gun. the only problem i would have is the clip size. its 12. this gun is a great spar gun mostly because you are quick and mobile, the freeze is very good, and it has a great fire rate. ive never seen it used before and i always get people telling me this gun is trash, but its very good. i recommend this gun. you can buy it at aimpoint btw.
