IMO, the entire point of 9x39 is if you want a quiet AK-ish gun. For an AR or a bolt gun, why not just use 300blk, 338 whisper, 350 legend, 458 socom, 510 whisper? An integral VSS or AK in 9x39 would be cool because they're iconic. A bolt gun in 9x39, not so much. K baffles kick ass for 9mm and 300b...

I have a reflex 450 bushmaster can with K baffles and I like it a lot. I've never shot the bowers 458, obsidian45, or hybrid46, so I don't know how they compare on 450BM.

This is by far the best option

See the link in my signature for solidworks files

No, the threads will be fine that way.

Yes, 0.036" is enough, especially since it is also supported by the tube.

I dont see why not

No.
No.

Do tiny tack welds every 120° or 90° on each baffle and just don't let it get too hot. If you're rotating manually, you're gonna have start & stop points anyway unless you're a contortionist, so I'd do every 90°tacks and alternate welding opposite sides between them I had a coworker weld my 300...

This was literally asked 5 threads ago...

He does some recores. Call him.

I cut it with a tiny lathe. See links below.

No

I have a feeling I will probably end up going with a symmetrical or asymmetrical clipping

those are literally the only two clip options.

Depending on the handguard, that can add a lot of weight. 17" handguards aren't usually designed for lightweight builds. Maybe a custom titanium handguard?

Probably not without an adjustable gas block

Good job. Can we see pictures?

as long as unused parts couldn't be assembled into a second suppressor.

this is key

Looks good. Those barrel ports are a little close to the chamber unless you want to try to keep 124 grain ammo subsonic

The stainless steel information center

The 300 series stainless steel can be "hardened" BUT only by "work hardening."

Sounds like your microphone is clipping the peaks off of the sound by quite a bit.

I'm having the following questions: 1) Pipe wall thickness - 1 mm. Is it enough strength? 2) Monocore will get thermal expansion when firing. The outer tube will also expand, but less (I could be wrong). I am afraid that the monocore will heat up and expand so much that the internal diameter of the...

I vote you port the barrel near the muzzle
