Dead Air would have made this easy for me had they just simply offered some version of the already wildly popular 2/3/4 ported brake a la PVA Jet Blast, APA Lil'B, 419 Hellfire. That omni directional "at least we tried" effort isn't my jam. I have a draw full of KeyMod brakes/flash hiders... well, like four of them. I'm not gonna use 'em. Wanted to 'em for when the can cleared jail, but ultimately decided I just don't like the interface for my bolt guns. Down to two things, first being I'm vain and they look like ass, and the second being no combination of washers/shims I tried could get them to time correctly and that annoyed me greatly.
I wonder when tbac will start selling their SR flash hiders. I have seen pictures of them but can’t find any for sale.
Use of an SR FH in a Dominus-SR would remove its full auto rating, so we have no plans to make more or sell them at this time. We only ever made a few engineering samples.
@Zak Smith this is excellent, thanks for the writeup. A while back (maybe at the introduction of the Gen 2 Ultra line?) there was a chart published that showed the 30 cal and 6.5 cal Ultras and the NR at the shooters ear from different rifles. I thought I saved it but can't find it. Is that chart still published and out there somewhere?
So would you say the Dominus is preferable to the Magnus on a gas-fed platform? Not concerned about full-auto rating, purely on gas system operation.
Between the Dominus-K-SR, Dominus-SR, and Magnus-SR, I pick the one solely based on how quiet I want it to be, vs. how much overall length I can put up with. The Magnus is overall quieter than the Dominus by quite a bit. The port pop might be louder on the longer can, but that impulse is very short compared to the overall outgassing of the suppressor (which is significantly quieter on the Magnus). This is on uppers than either run fine suppressed or are tuned to run with an Ultra5 or Dominus-K-SR (ie, a short can).
To answer your question with a different criteria, the Dominus-SR is probably my favorite on a gas gun overall because it's not too big but suppresses well.

I actually have a Dominus K-SR and I’m considering picking a Magnus, but my chief concern is interoperability between gas powered platforms without adjustable gas (e.g. KAC, ignoring the muzzle device problem for this conversation) and my bolt guns.
FWIW, using an analog screw-type adjustable gas block, on at least one rifle, I tried to find a setting that would run with a Magnus (or maybe it was a 338 Ultra) but would NOT run with a Dominus-K-SR, and I could not. But there was a difference from suppressed to unsuppressed.
In fact, once I went out with like 3 different SCS weights, 3 different bolt carrier weights (full aluminum to Nat'l Match), and different loads trying to find combinations that "would" work, but I ended up finding almost no combinations that would NOT run.
If you end up with a little too much gas and it runs too fast to lock back or shoulder-jams the next round, try (1) switching to the SCS, and if that's not enough, just add a little weight to it.

I went with the Magnus-HUB for my AR10, and bought direct thread as well as the DA Xeno, we will see which one I like better. I did not care about length, this gun is not built for run and gun. I have a SBR 300BLK suppressed for that.
If you're interested, shoot me a PM & I'll explain to you what I did to solve this exact problem on an SR-25. I don't know that it's THE way to do it, but it looks good & has been working fine thus far.
I have Ultras in 5" and 9", as well as some older cans from TB, as well as a take down. For my money, the Dominus hits the sweet spot in sound suppression, weight and length. I have a 1/2 off cert that I've been sitting on because I'm an idiot, but I'm fairly certain I'll use it on a Dominus CB. However, more than half my shooting is with gassers, and a fair amount of that is tactical rifle matches (read run and gun). In those matches, it's common to fire 40-50 rounds in 60-70 seconds. I've taken an IR thermometer to the range and checked the temp of the can immediately after showing clear, and I've seen temps between 600° and 700°. Yikes. For my use case, the extra durability of the Dominus makes me feel better.
My two 9" cans are long enough to make my bolt guns feel unwieldly when shooting on barricades at a PRS style match. The 9" Ultra on my Dasher is just silly quiet, though. Fred's comments about the Magnus have me thinking I need one, but I'm not sure why. My Ultras are quiet enough to send a shot or two without ear pro, and no can will make a centerfire rifle quiet enough to shoot for an extended time without ear pro. There's the cool factor of a super quiet rifle, but I can't see it makes any practical difference. I'd be interested to know if there are any numbers comparing the recoil impulses of the various cans. If the Magnus provides more "braking action", well then that's another story altogether.
None of that is probably relevant to your exact situation, I guess it's more a description of mine. I'll say this, if I were just getting into the suppressor game, I'd have a Dominus as my first can.

A bootleg adjustable carrier will solve this problem. I run them on my SR15's and Colts. Gemtech did or does make a 7,62 adjustable carrier as well.
Do the cb mounts have to be timed if you are not planning to shoot the rifle without the suppressor on the mount. Don’t want to loctite the cb to barrel, may want to shoot the rifle without suppressor and don’t want a brake on it
So just tighten the cb to barrel and screw the can on and should be gtg? I assume you used high temp loctite to lock them together
If you do not loctite the brake to the gun it will come off with the can. Guaranteed.
If you need to remove the muzzle device often, use the CB FH

In case anyone was curious how the new TBAC Magnus-HUB sounds on a 16" .308 Win... It sounds amazing.
