Nerf Knockout hopper by ThatBoyJacob

Last crawled date: 4 years, 2 months ago

A 3d printed rail attachment that goes onto the knockout to decrease reload time. There isn't an easy way to print without supports so I recommend curve side down and print with it vertical. The only mods needed to the knockout are to extend the breech travel and trim the edges of the breech to allow rivals to gravity drop in.
