Previously did all design work at CGS Group, 2014-2024.
What's even crazier is OSS's lawsuit against TDS for patent infringement. I'm guessing TDS is spending too much money on lawyers to defend against a stupid and blatantly false lawsuit, and not enough money on testing and production. Just a guess from my end and the details of the lawsuit are sealed because of intellectual property issues - but I look at both suppressors and it would be like McDonalds patenting a hamburger for this to work out for OSS.
Here's some more non-scientific anecdotal information: I had it out shooting some VTAC drills today, and took my ears off for several drills just to see. No discomfort at all. And the shots never would register on the PACT shot timer on my belt throughout. Which was impressive, because we've seen several k-style suppressors at matches and they always registered on timers with no issue.
Mk262 clone ammo through a 12.5" upper. Totally happy!

You guys that feel that this design is pretty readily done without DMLS.... how (and from what) would you make the spiral thingy between the baffles and the wall? Looking at some radiographs of the Strix and the Bantam, I see what you mean now, but my creativity needs a jog since I’m not a machinist.
My best idea so far would be to abandon the spiral and use a perforated inner wall and a few perf’d “washers” between the inner and outer walls. But, this sounds like an expensive way to make a shitty can.
Shoot me a PM, if you don’t mind.

Silence.
I'm a mechanical engineer and hobbyist machinist and don't see how it could be done with traditional machining. Or at least not without a whole lot of complicated welding, extra weight, and resultant warpage problems. And it sure wouldn't be one homogenous piece of Inconel when you're done.
Waiting to be proven wrong.
Doesn't really matter though. I'm super happy with my purchase and shared this here for anyone who might be looking for a suppressor with similar traits. If someone doesn't like it for whatever reason it's no skin off my nose.

Traditional CFD models airflow through a suppressor, and typically ignores the moving bullet as it passes through the can as it's just too complex for most software programs. Superheated gases escaping from a rifle bore act more like plasma than air, so almost all of the assumptions are wrong when you use air flow through an open suppressor. Add in a moving bullet that blocks the bore as it passes through, and expanding gases (acting more like plasma) that change temperature and pressure constantly and you have a level of complexity that a steady state model just can't accurately portray.
However - I'm pretty sure the literal rocket scientists at Oak Ridge National Labs understand those issues and know more about plasma flow than just about anyone else out there, and they have access to supercomputers that can model things at a MUCH higher complexity level than most typical engineering groups. I wouldn't be so quick to lump their modeling efforts in with typical CFD.
