Dominus-SR Suppressor 30 Caliber

The TBAC Dominus-SR Suppressor is Thunder Beast’s high performance hard use full auto rated 30 caliber suppressor. It is constructed from high quality titanium making it a very lightweight option when compared to most other suppressors. This suppressor offers unmatched accuracy and retention. If you have used ultra-suppressor, the Dominus meters right in between an Ultra 7 and 9. The 6.95-inch DOMINUS-SR meters at 137 dB (milspec left/right) and 126 dB at shooters-ear¹ on a 20-inch .308. These numbers are from a PULSE system. The SR quick detach mount offers a rugged retention system that will always stay locked in place and lockup the same after being taken off and put back on. There is no noticeable shift after taking the suppressor off. This suppressor is compatible with only the SR brake in either .30 cal or .338. The SR mount uses a novel paw and cam-path system to ensure that “full lock up” can happen in either of the two adjacent detent slots for any given final shouldering position of the suppressor on the conical brake shoulder. This categorically avoids the “off by one” problem that many “clicky” mounts have. The SR mount has the exact same accuracy, repeatability, and return-to-zero characteristics that all TBAC precision suppressors are known for.

SUPPRESSOR DURABILITY RATINGS

There is general confusion as to what firing schedules different suppressors on the market can actually withstand. There are “full auto”-rated suppressors that will fall apart after a few mags of full auto, and on the other hand, there are some “precision rifle suppressors” that will actually withstand a lot of abuse.

DOMINUS-SR CATEGORY: “HARD-USE/FULL-AUTO” [HU/FA]

Lifetime to exceed at least 10 SURGE cycles on a 10.5″ M4 / MK18.

One SOCOM/SURGE CYCLE comprises

Mag 1: 1 round/second
Mag 2: 2 rounds/second
Mag 3: 1 round/second
Mag 4: 3-5 round burst
Mag 5: 1 round/second
Mag 6: 2 rounds/second
Mag 7: 1 round/second
Mag 8: 1 continuous burst
Outlined in Section 3.6.1.i. in Solicitation H92222-17-R-0011

The basis for this is the SOCOM/SURGE specification, which is a common heavy firing schedule specified in many military solicitations. One SURGE cycle is 8 magazines fired in this pattern, with magazine changes happening as quickly as possible. After a full 8-magazine cycle, the suppressor and firearm is allowed to cool to ambient. This firing schedule significantly exceeds the worst-case application of assault rifles and baffle rifles. A milspec M4 needs service and inspection after each cycle to keep operating.

Most common 17-4 steel muzzle brakes will be eroded significantly or have critical surfaces destroyed after 2-4 SURGE cycles. How often has your firing schedule destroyed your muzzle brake? If the answer is never, you haven’t even exceeded half of what this suppressor can take.

Suppressors in this category will still have minimum barrel length ratings for most cartridges.

The SR muzzle brake will have a replacement schedule if fired “to the letter” of this schedule. It is recommended that the SR brake be replaced when visible deformation of the brake ports happens, or the suppressor simply won’t fit over the brake anymore.
