Since apparently the 500 Jeffery was much less of a challenge to build than I thought, and EForms has been running well recently, I grabbed some 20mm parts and will be doing the world's dumbest home-built DDs.
Have an old Colt M12 parts kit, a full sized vulcan barrel, and a 16" barrel stub.
The remill on the old colt will be decently easy. Not expecting any issues with that, I've got the semi conversion figured out on paper, and the rest is just welding/machining. Making a magazine will be fun but not impossible.
It's the second gun that I'll have issues with. I plan to make a stubby truck rifle just for giggles. 16" barrel means I can throw a stock on it.
Plan to make it look like the Noreen ULR but with Downs syndrome.
My issue is there is zero information on bolt design, and just using shear calculations, and some messing around, it looks like I'm just going to make the receiver and bolt as a very large mosin.
If anyone has built a 20mm single shot/non-auto 20mm, advice would be super appreciated.
