Description

Thunderbeast Arms suppressors DO NOT include Corresponding Muzzle Device/Mount. Thunderbeast Arms Mounts are sold separately. Click Here to See all Thunderbeast Arms Products.

The DOMINUS-K-SR is the “Short” (Kurz) version of the DOMINUS-SR. At 5.45 inches long and 10.0 ounces, it is 1.5 inches shorter and 2.5 ounces lighter than the full size DOMINUS-SR. When mounted, it adds only 4.87″ to the barrel overall length.

The DOMINUS-K-SR is our super short, hard-use/full-auto 5.56 and .30 caliber suppressor. It delivers five principal design goals:
1. full-auto durability;
2. light-weight titanium construction;
3. best-in-class repeatability, accuracy, and retention;
4. suppression level similar to Ultra series; and
5. extremely short length added to weapons systems.

It is a true light-weight micro-sized “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 DOMINUS-K-SR meters at 145 dB (milspec left/right) and 134 dB at shooters-ear¹ on a 20-inch .308 bolt-action rifle.

On 10.3-inch “Mk18” AR-15 SBR (without any special tuning) shooting Mk318 5.56 ammunition, it meters at 145 dB muzzle (milspec left/right) and 144 dB at the shooter’s ear. Note that this is the same as the shooter’s ear dB for the full-size DOMINUS-SR for an untuned upper, which means that the shooter is experiencing primarily noise from the action as opposed to noise from the muzzle report.

These are numbers from our PULSE system which should be considered definitive, supplanting all data from the older 2209 sound-level meters.

The DOMINUS-K-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-K-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).
