Nerf Rival Knockout T-pull by Ehdrien
The original Knockout priming handle thingy is rather weird and bulky. The Knockout T-pull by Ehdrien is changing that making it much more comfortable to prime the blaster while giving it a smaller profile at the same time.
This original handle can be removed with two screws revealing a hole in the bottom of the priming bar large enough for a M5 bolt. The 3d printed spacers/handles keep that bolt centered on the priming bar and increase the diameter of the bolt, where your fingers grip it, for comfort.
This part will come with a M5 bolt and locknut so you don’t need additional hardware.
This modification requires no cutting/drilling. Simply unbolt the stock handle and bolt on the T-Pull.
