Description
The DOMINUS-SR is our high-performance hard-use/full-auto 5.56 and .30 caliber suppressor. It delivers four principal design goals:
1. full-auto durability;
2. light-weight titanium construction;
3. best-in-class repeatability, accuracy, and retention; and
4. similar suppression to the Ultra series .
It is a true light-weight “Go To War” suppressor and is perfect for 5.56 assault rifles and .30 caliber battle rifles, including SBR variants. It retains the accuracy and repeatability TBAC is known for. It’s equally at home on a 0.25 MOA bolt rifle on the 1500-yard range as it is on a MK18 in the CQB house.
The 6.95-inch DOMINUS-SR 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-SR features our “SR” quick-attach/detach mount to provide Secondary Retention, retention during hard-use and heat cycles, and precision-rifle-level accuracy.
The DOMINUS-SR is rated for what we call a “Hard-Use/Full-Auto” (HU/FA) firing schedule. We specify this as surviving at least 10 cycles of the SOCOM/SURG firing schedule. The SR mount keeps the suppressor tight throughout each cycle and is a key feature in enabling this rating. After 10 SOCOM/SURG cycles, a test unit metered 1 dB louder than a brand new unit. The SR mount still functions and is easily removed at the end of the series of cycles (see video on the right-hand column).
The DOMINUS-SR is shorter but fatter than the ULTRA series, and about the same weight per volume. It is 6.95 inches long and 1.8 inches in diameter. The DOMINUS-SR itself weighs 12.5 ounces. The SR brake weighs 3.5 ounces. The SR brakes are compatible with all SR series suppressors (eg, DOMINUS-SR, 338 ULTRA SR).
