Thunder Beast Arms Releases the New Dominus Suppressor

Thunder Beast Arms Corporation just released a new .30 caliber silencer they are calling the Dominus, which is Latin for master.” It's 7-inch long, 1.8-inch in diameter and is a tubeless design. The construction on this can is so well done that the welds are not visible.

Coupled with an SR (Secondary Release) mount the weight will come in at 12.4 ounces total. The main feature of the SR mount is that it acts as a secondary, fail-safe, locking mechanism to retain the suppressor on the muzzle brake in all circumstances, unless explicitly removed on purpose, by hand. It reduces the number of turns required to mount the suppressor due to a coarser thread and enables Quick Mount and Quick Detach functionality of the mount. The mount is mechanically very simple and user-level maintenance is possible.

A slightly lighter version with their CB (Compact Brake) mount will be available that should drop the combined weight down to 9.5 ounces.

Both versions of the Dominus meter at 137 dB (milspec left/right) and 126 dB at shooters-ear1 on a 20-inch .308. This puts it right between Thunder Beast's Ultra 7 and Ultra 9 suppressors. These are numbers from the PULSE system which should be considered definitive, supplanting all data from the older 2209 sound-level meters.

Initial testing has shown that the Dominus will survive at least 10 cycles of the SOCOM/SURG test.

The SOCOM/SURG test is a suppressor torture test designed by U.S. Special Operations Command that fires about 240 rounds in about 4 minutes through a suppressor at a rate of 1 round per second for the first magazine, 2 rounds per second for the second magazine, 1 round per second for the third followed by a burst of 3-5 rounds, then repeated at 1 per second, 2 per second, 1 per second and the eighth magazine is a sustained full-auto dump. The silencer and brake are allowed to briefly cool after each magazine so it can be repeated.

In addition to that stress test, SURG must prevent operator contact or sustained contact burns from the suppressor (or equivalent) through 1 layer of standard military duty uniform material after firing 210 rounds in 7 minutes at a rate of 1 round every 2 seconds ± 0.2 seconds. A contact burn will be defined as a peak temperature over 160°F in 1 second of contact. A sustained contact burn will be defined as a peak temperature over 160°F in 5 seconds of contact.

The brakes only last 4 cycles and then need to be changed. It is a firing schedule that probably does not represent a real-life application of a precision rifle can, but it probably duplicates overall life through quick immersion and stress in adverse conditions.

Most stainless-steel brakes will come apart in this kind of testing. The metal gets so hot it can melt and all the pressure at the muzzle just starts to push the molten metal out of shape.

As a result, this is the first silencer from Thunder Beast Arms Corporation that can perform double duty.

In the past, their high-end precision cans were best suited for use on high-end, or, at least dedicated precision rifles. They were all titanium and so lightweight that the first time we picked one up we felt like we were holding a cardboard paper towel roll. It was definitely not something you would want to mount on an SBR or any type of rapid-fire or full auto weapon.

Of course, we have used TB's 556 Takedown model, which is designed for that very purpose. So, this new silencer is a best of both worlds solution if you want to acquire a higher-end suppressor to run 5.56 and 7.62. MSRP is $1495.
