Hmm, interesting. Trying to figure out if I really need something to fit between a Dominus-SR and a 338 Ultra SR. I'm assuming this will be available with the SR mounting system, right?

No plans specifically at this point. We'd have to make one and test it to see if there's any advantage. Sometimes there's not (ie, why we dropped the 223 Ultra 7 in favor of the 6.5 Ultra Gen2). If it's something you're interested in, please shoot us an email so we can gauge demand.

Awesome, I'm definitely interested. I have a 338 ultra for my 30 cals and up and a 6.5 Ultra 5 for my hunting rifles. I think a 6.5 magnus would be perfect for the match, 223 trainer, and varmint rifles if it offers a bit more suppression than the 30 cal bore.

@Zak Smith are you going to offer CB or SR “hub” attachments in 1.375x24?

Getting to the point where now I have CB and SR suppressors, and a SiCo with 1.375x24. It would be cool if you made an SR mount that threaded into a 1.375x24 suppressor so I could further reduce muzzle devices (and not have to rely on 3rd party CB mounts like the Area 419).

Im in the same boat. Probably a better bet to get a third party to make one

I'm the video he used a CB flash hider so I guess the CB hub is a thing can't speak to the SR hub but I feel like unless it has a lock then the SR wouldn't make sense.

On the HUB questions--

This is our "HUB experiment", to see how it goes. From our perspective, HUB has the potential to be a liability because even if everything else is "good", that interface can come loose; and then there's the issue of problems with other mounts and brakes. The bottom line is that if you get the HUB version, you should know what you're doing and everything behind the can body (and any damage it causes) is your responsibility.

This is in contrast to the CB or SR systems in which we control (ie we made) the mount interface on the can and the muzzle device and can ensure compatibility, repeatability, thermal stability, etc.

The SR system will not be ported either direction to HUB; it would undermine the full auto retention capabilities of that mount system.

By SHOT I don't think we'll have a CB/HUB interface but we may end up making a "reference" version of it down the line.

The Magnus will have 3 distinct versions, CB, HUB, and SR.

All you guys who are invested in other mounts and want "the quietest .30 cal can" can get the HUB version and go to town. When you want to step up to a superior mount system we have the CB and SR waiting for you :ROFLMAO: 🤣 🤣

On the gas gun question--

This one was designed and developed on bolt guns because you will never get a gas gun that quiet. That said, in broad terms it will perform very similar to a 338 Ultra (BA or SR) on a gas gun. We'll get numbers on some exemplary platforms soon

Let's be honest - most of us who believe in TBAC have invested heavily into sr or cb or 338 brakes because we know how great they are and Hub isn't really a necessity. Those who are vested in hub mounts might get a magnus, opening up some more market share for them. Now let's leave Zac alone so he can get the CD matches posted 😁

I like your honesty on HUB. I don’t see much of it in the industry. It is a glorified direct thread mount with no easy ability to tighten it to a very confident and obvious semi permanent level of torque. But it is popular. We have a few models now with the interface, so this is no negative commentary on any brand or can.

Built in mounts (like you are saying) are superior in my opinion, but customers look at dozens of systems and want to leave options open for future choices. The only thing at odds with that is that any mount added is integrated on that direct thread foundation of HUB. It seems that doesn’t bother the customers much, and they will probably even prefer locking mounts integrated with HUB.

The bolt gun performance is really market leading. Gas gun numbers with right and left shooter ear on an unmodified, non adjustable gas, DI .308 rifle that runs without a can would be interesting, but for the bolt guns this can you are showing is really pushing boundaries. At 125 I can see why a person might buy a can solely for the bolt gun application.

Congratulations on the successful development process and your hard work in the precision bolt gun space.

I am a bit skeptical, but my belief is that there are few innovators in suppressors and TBAC is looking like one of the more dedicated companies in development.

With regard to the missing post, adjustable gas blocks can have too little "sensitivity" depending on the underlying gas system of the upper. This is especially true on AR-10's. I've tested big-block uppers from 12" up to 20" and haven't had a problem getting them set up to run anything from a Dominus-K up to the 338 Ultra SR (with a single setting), however, sometimes the screw-adjustable gas blocks are sensitive to like 1/8th of a turn.

I guess you're taking to me. I could've sworn I posted but can't find it.

Anyhow- I've played with the superlative and sentry and neither were fine enough to really dial in my nomad L with everything from a JP SCS h2 to a custom slash 12.5 oz rifle buffer on my 16" rifle gas 308. I can make it run there's just a very narrow band of adjustability relative to say my rugged razor.

Could definitely be user error but that's the highest backpressure can Jay has tested.

Even when it runs acceptably I've determined that for me lower backpressure is better for a large frame.

I've seen the tbac vids of y'all running that 12.7 308 gas gun with the dominus and it appears to run great so I figure there some Indian arrow going on too.

That dominus k on a 16" rifle gas 308 would be a sweet Killin rig.

What gas block do you recommend?
It feels like my SA and SLR has much less fine resolution than an 1/8 a click at the detent points. Maybe I should just ignore the detent points.

Thanks- I might try a non-detent set screw type as I find the detents too wide on a high backpressure 308.

Oh and sorry to derail.

Congrats on the new king of hush!
Looks like a freaking awesome can!
Hope I can here it in real life someday.

Pure sonic crack probably sounds crazy.

There are a number of cans that suppress the blast to a dB level below that from the sonic crack, when measured from milspec right/left positions. This adds a little complication to comparing their suppression levels, but disentangling it is easy with the PULSE. We'll have a video that explains it coming soon.
