A challenge for you tinkerers Answered

Picture of

Well, I'm planning on picking up a Piranha PMI USP paintball pistol. One of the attractions was the full size internals, making it very mod-able. While surfing, a mysterious offer appeared on ebay, a USP with "custom speed-feed". Anyone who owns a mid/low range paintball pistol is familiar with the pains of reloading in combat.

From what I understand, 9 round spring loaded tubes are used as magazines (I believe the seller made them from ten round tubes and a spring); so one can interchange them quickly without pouring in individual rounds. A total godsend.

While it's pretty hard to get a grasp on the mechanics without holding the gun; it looks like the gun has just been modded to accept 10 round tubes. It seems deceptively simple.

Thus, the challenge is creating the 9 round magazines correctly and finding out how they 'lock into' the marker. Man, I hope my gun doesn't get screwed up by trial and error.

Unless someone gets it up and running first, I'll be sure to make an instructable; and credit whoever helps me out.

Oh, the pictures the seller provided might prove useful, lol. And heres the manual for the USP

Oh my, I wish  I still had my USP for this. But I traded it on Techpb.

This looks fairly easy to do and make. I could mod a USP for you like this if you would like to pay me to do it.
