I love building light machine guns. This one in particular uses a cam system to simultaneously drive the feed cylinder and the firing pin at insane speeds. For example, if you put a 90 RPM n20 motor in this, it's going to fire nine times every second you hold down the trigger.

After finding out Domi_dks is actually making his own mag-fed thing, I have held off on making mine until he releases his magazine-fed launcher and I can model the magwell for his magazine geometry.

By the science of "good enough," this firing mechanism is perfect. Also it's got ejection going for it now. Still no idea how it's gonna cycle though.

Me and my homeboy needed a way to arm us and our army of two other child soldiers. After I experimented with using pen parts as ammunition, which turned out to be a flop, I came across @domi_DKS's toy shotgun shells. Currently developing something funny and hopefully fully automatic with it!
