The TBAC Dominus-CB is a high-performance .30 caliber suppressor renowned for tubeless construction. Designed with a 360-degree fully-welded baffle core, this silencer’s durable construction has rock-solid POI repeatability and accuracy.

Based on the TBAC Dominus-SR, this suppressor uses the CB mount instead, not full-auto rated but impressively a shorter, lighter, and more cost-effective model! Compared to the Ultra 7, the Dominus-CB is .75 inches shorter and larger in diameter by .30", but about 2 dB quieter. Not only is its titanium construction lighter, but keeps to the proven durability of Thunder Beast Arms Corporation suppressors.


At 6.25 inches long and 1.8 inches in diameter, the Dominus-CB is shorter but larger in diameter than the Ultra series, and about the same weight. The Dominus-CB itself weighs 9.6 ounces while its CB brake weighs 2.6 ounces. All in all, with a solid yet lightweight construction and high suppression performance, the Dominus-CB joins the lineup of reputable AND dependable suppressors.
