My Dan's Pistol was super fun to use as a pump action, but it kept bending darts. Since my Foxbat has always been reliable, I thought I'd convert it to pump action. This is not the most svelte mod - attempt numero uno - but it works well. For this mod, you must use the picatinny top front slide and the one-piece side panels from SillyButts.

M4 Hardware to mount on the picatinny. 3 mm pins to mount the rollers.

In its current incarnation, you'll need to remove ~2 mm of material from the bottom rails of your FoxBat. Otherwise, the pins rub against it. This has no effect on the functionality of the bottom rail.

I'll likely move to larger rollers on future iterations, so that the pins can be moved outward, away from the bottom picatinny rail.
