Short monocore 9mm.

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Form 1 cleared in 20 days btw

Any good posts here about monocore designs? I've done an sd like build that's mouse fart level but there was a lot of room for error in that. I got about 6 inches of length that can be milled out and the od of the core is going to be 1.875 inches. Really too short to guess randomly. I rather stick to 3 axis milling but I could free up the 5 axis if I'm willing to wait a long ass time for it to be free for my nonsense.

100% aluminum. I think its 6061 but it's been in the scrap pile so long

The male threads are for? Just work holding?
1.875x6 should be plenty for 9mm subs.
Something like the YHM Sidewinder wouldn't be unpossible on 3 axis.

Male threads are for a quick and dirty end cap

Less Blast chamber (more = FRP) and more baffle chambers.

When I did my 5.56 can a large blast chamber did a lot for making it quiet but I'm by no means know what I'm doing and 9mm isn't even in the same ball park.
