Retaliator Open Pump Kit Project

thingiverse

I've created a full 3D printed pump kit for the Nerf Retaliator. The project's premise is to use mostly 3D printed parts, resulting in a design that may not be the strongest but should meet the needs of most modders out there. Be sure to keep checking back for updates. At this point, the priming arms are too thin and need to be made wider to improve their rigidity and provide more clearance for the screw securing the arms to the shell. To print both sides of the priming arm, you'll need to mirror it in your slicing program. The slider will require supports. You'll need 4x 4M 8mm countersink screws and 4x 4M nuts to assemble the kit. I've uploaded an improved priming bar with excess material cut away around the bolt sled interface. I've also increased its thickness and added a groove, making it more resistant to bending and buckling. There's another version of the REV 2 priming bar that allows for the use of other types of M4 bolts. I'm still working on some compatible pump grips, so stay tuned! I've added two more arms to the pump kit to address issues with pins shearing off. I made modifications to Rev 3, which uses an M4 screw to interface with the bolt sled and has a cutout for an M4 nut to keep it in place. Rev 4 is a nut-free version, with a hole diameter of 3.5mm that can be threaded with an M4 screw or another similarly sized imperial screw. I've created more priming bar options! Rev 5 builds on version 4 and has more material around the screws that connect the bars to bolt sled. Rev 6 is similar to Rev 5 but has filled-in bars.
