Description
The DOMINUS-CB is a high-performance .30 caliber suppressor. It delivers three principal design goals:
1. light-weight titanium construction;
2. best-in-class repeatability and accuracy; and
3. similar suppression to the Ultra series .
The DOMINUS-CB is based on our DOMINUS-SR suppressor, but uses the CB mount. Please refer to the DOMINUS-SR specifications page for more information about the SR. The CB mount derates the retention level from full-auto capable but the resulting suppressor is lighter, shorter, and less expensive vs. the DOMINUS-SR.
Compared to the ULTRA 7, the DOMINUS-CB is 0.75″ shorter and larger in diameter by 0.30″, but about 2 dB quieter. It meters at 137 dB (milspec left/right) and 126 dB at shooters-ear1 on a 20-inch .308. This puts it right between the Ultra 7 and Ultra 9, These are numbers from our PULSE system which should be considered definitive, supplanting all data from the older 2209 sound-level meters.
The DOMINUS-CB features our “CB” mount system for interoperability with all CB muzzle devices, for users who have other ULTRA series suppressors.
The DOMINUS-CB is shorter but fatter than the ULTRA series, and about the same weight per volume. It is 6.25 inches long and 1.8 inches in diameter. The DOMINUS-CB itself weighs 9.6 ounces. The CB brake weighs 2.6 ounces.
