Thunder Beast: Dominus K SR Suppressor .30 Cal
SKU: Thunder Beast: Dominus K SR Suppressor .30 Cal | Manufacturer ID: DOMINUS-K-SR
The Dominus-K-SR suppressor is a great choice for SBR rifles and precision rifles alike. 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. TBAC specifies 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). Specifications. Maximum rated caliber.30 caliber, up to.300 RUM. Material.

Outlined in Section 3.6.1.i. in Solicitation H92222-17-R-0011. The basis for this is the SOCOM/SURGE specification, which is a common heavy firing schedule specified in many military solicitations. One SURGE cycle is 8 magazines fired in this pattern, with magazine changes happening as quickly as possible. After a full 8-magazine cycle, the suppressor and firearm is allowed to cool to ambient. This firing schedule significantly exceeds the worst-case application of assault rifles and baffle rifles. A milspec M4 needs service and inspection after each cycle to keep operating. Most common 17-4 steel muzzle brakes will be eroded significantly or have critical surfaces destroyed after 2-4 SURGE cycles. How often has your firing schedule destroyed your muzzle brake? If the answer is never, you haven't even exceeded half of what this suppressor can take. Suppressors in this category will still have minimum barrel length ratings for most cartridges. The SR muzzle brake will have a replacement schedule if fired "to the letter" of this schedule. It is recommended that the SR brake be replaced when visible deformation of the brake ports happens, or the suppressor simply won't fit over the brake anymore. APPLICATION NOTES.
