Nerf Knockout – Brass breech parts

I made these parts in order to help with adding a brass breech to my Nerf Rival Knockout as well as add a threaded muzzle for accessories. I also added short dart storage while I was at it.

the short dart storage requires shell cutting to fit. I’ve included an image that shows what I had to cut. You will most likely need to sand the dart holes in the holder smooth after printing. Wrap sand paper around a pencil and sand until your desired dart fit. There was barely enough room to squeeze three darts between the screw posts in the blaster so this felt like an acceptable compromise.

Many of the brass related 3D printed parts will require epoxy to glue them in place as well as provide (hopefully) air tight seals.

I will not make instructions for installing these parts or the brass breech. If you want more info on brassing your knockout please refer to WalcomS7’s “hush puppy” video. It’ll be pretty much the same process except some of the PVC and tape he had to use are replaced with 3D printed parts.
