Nerf Rival Apollo Pump Action Mod

The Nerf Rival Series is a ton of fun to play with your kids, however there is always room for improvement to some of their designs. The Apollo in particular has a priming mechanism that forces the player to awkwardly reach over the gun to prime the next shot. I found a great Mod on thingiverse to turn it into a more typical pump action, and modified the design further to be easier to print on a smaller 3D printer, as well I changed it to use 8mm rods and glue instead of bolts and metal bars to make it much easier to assemble for those without metal cutting and drilling tools. The 3D files can be found at the following links.
