Thunder Beast Ultra 7CB



Thunder Beast Arms ULTRA 7 SUPPRESSOR

Lightweight Precision Rifle Suppressor, .30 caliber, 7 inch.

The ULTRA 7 is our highly efficient compact .30 caliber precision rifle suppressor. It is best for applications where a compact form factor is important but excellent suppression is still required.

The ULTRA 7 will suppress a typical .308 bolt-action rifle down to approx 134-136 dB1. The ULTRA 7 weighs just 9.7 ounces.


The ULTRA series represents a revolutionary improvement in titanium precision rifle suppressors. We took everything we’ve learned over the last half decade building the best precision rifle suppressors in the world and put it into the ULTRA design. The ULTRA series offers unprecedented light weight and class-leading suppression levels.

Compared to the prior 30P-1/30CB9 series, the ULTRA series is 25-30% lighter, 4-5 dB quieter, and much stronger. The ULTRA series holds the same precision and repeatability as the 30P-1/30CB series.

The .30 caliber ULTRA series includes three suppressors: 9-inch, 7-inch, and 5-inch versions are available. They are available in either our Compact Brake (CB) “Thread Over Muzzle Brake” (TOMB) mount or in a direct thread mount. The CB mount and direct thread mount have equivalent accuracy and repeatability.

With the CB mount, the suppressor mates to a conical shoulder on the brake and locks up rock solid and extremely tight. In direct thread configuration, the ULTRA suppressors use a heat-treated 17-4 thread insert and initial blast shield. The .30 caliber ULTRA series suppressors also have the flexibility to be changed from direct thread to CB mount and vice versa via a simple factory service operation, in case your needs change. This is accomplished by removing or replacing the default brake from the direct thread version.

The ULTRA series is constructed of titanium with a fully-welded core. This material and construction provide a great strength to weight ratio. It can take whatever your precision rifle can dish out.

The ULTRA baffle stack was completely redesigned, but retains the principles that made the 30P-1 stack such a great precision and long-range suppressor. Thunder Beast Arms Corp suppressors have racked up impressive results at long-range field shooting events nationwide, and have been the most popular suppressor used in the Precision Rifle Series (top 50 competitors) for three years running.

Many long-range shooters prefer shooting suppressed because the muzzle blast and concussion is eliminated, while the recoil impulse is reduced and smoothed out over time. The net result is that the rifle is easier to shoot and it’s easier to make hits. Communication with your spotter is easier because the need for hearing protection is reduced.

The ULTRA series was designed around .308 for maximum flexibility and is rated up to .300 Winchester Magnum (18″ barrel), but it’s the ideal suppressor for the most competitive mid-sized cartridges for long-range shooting such as .243 Winchester .260 Remington, 6.5 Creedmoor, 6.5×47 Lapua, 6.5-284 Norma, and 7mm Remington Magnum & WSM.

1 Reviews For Thunder Beast Ultra 7CB

  • Joshua Scalise8/11/2016

    Bottom line: If I could go back and start over on my suppressor choices, This would be my one and only rifle suppressor.

    I cant speak highly enough about this can. My first suppressor was a steel 5.56 YHM phantom QD. Rock solid, built like a tank, but extremely heavy (18.5oz) and limited to .22 caliber ammo. The TBAC Ultra CB 7 is half the weight (9.7oz), works with anything up to 30 caliber, and to my ear sounds just as quiet as the heavier & longer YHM Phantom. I love having the ability to use 1 suppressor for all of my rifle calibers. The phantom QD has very heavy duty thick threads that are not easily damaged, while the Ultra CB has very fine threads which could be easily cross-threaded if you try to put it on in a hurry. Once mounted, it is pretty solid. My only gripe is the fine threads on the Ultra can be cross threaded, and I have had a few instances where the can started coming loose despite being hand-tightened (this is not abnormal for QD suppressors). Keeping that in mind, be very precise when mounting, and routinely check to make sure it is fully seated during use. I do not notice any zero shift, but I do notice (sometimes significant) accuracy changes for various ammo (commercial and reloaded). Sometimes the can opens up groups pretty bad, sometimes it tightens them up. I have taken good care of it, but if I dropped it on a concrete floor or on gravel I am not worried about anything beyond cosmetic damage. Titanium is surprisingly resilient. There is a reason it is so expensive despite being one of the most abundant metals in the earth's crust: It is very very durable and thusly difficult to machine. This translates to durability and damage resistance. Too bad the CB brakes can't be titanium also. Titanium is also more resistant to heat warping and heat expansion than steel.
