Thunder Beast Arms TBAC Dominus SR

The Dominus SR from Thunder Beast is a high-performance hard-use suppressor designed for both 5.56 and .7.62. The goals behind the Dominus SR were to create a full-auto suppressor from light-weight titanium similar to the Ultra series. While rated for full-auto, it maintains the accuracy and repeatability Thunder Beast is known for. It’s right at home on both a MK18 and precision bolt gun.

The 6.95-inch Dominus SR comes in at 126 dB at the shooters ear with 308, and below hearing safe at the muzzle. These numbers put the Dominus-SR between the Ultra 7 and Ultra 9 in terms of performance while being shorter than the Ultra 7. The additional volume is achieved through a larger diameter and tubeless design.

The “SR” in Dominus SR stands for Secondary Retention. A quick-attach/detach mount provides both a taper surface for precision rifles, and a secondary retention to ensure the suppressor does not back off under hard use. The Dominus SR is rated for a “Hard-Use/Full-Auto” firing schedule. Thunder Beast specifies this as surviving at least 10 cycles of the SOCOM/SURG firing schedule.
