Thunder Beast Ultra 9CB



Thunder Beast Arms ULTRA 9 CB SUPPRESSOR

Lightweight Precision Rifle Suppressor, .30 caliber, 9 inch.

The ULTRA 9 is our full-size .30 caliber precision rifle suppressor. It is best for applications where maximum suppression is key.

The ULTRA 9 will suppress a typical .308 bolt-action rifle down to approx 132-134 dB1. The ULTRA 9 will suppress a typical .300 Blackout bolt-action rifle to about 118-120 dB shooting subsonic ammunition. The ULTRA 9 weighs just 11.9 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.

4 Reviews For Thunder Beast Ultra 9CB

    Very impressed with this can - on a 300blk bolt rifle and it's stupid quiet, very light, looks great, and of course doesn't impact accuracy aside from a slight poi shift.

  • OPSC7/27/2016

    This can has excellent sound suppression capability and the point of impact shift is consistent after multiple range visits. I zeroed in a new rifle (.300 win mag) with the brake only and it sounded like a jet burner (disclaimer, barrel is short relative to shooter). Attaching the can made a world of difference. The range master claimed "I wouldn't believe it if I didn't hear it."

    I let a few people shoot the rifle/can and due to other range activity plus the can, I didn't hear a few of the rounds go off and I was standing right beside him!

    I bought a mirage cover for the can just in case because this was my first purchase. I ran it on the can the first day out and took it off toward the end of the day. Without it, the heat wave off of the can is enough to really mess with the image through your scope. I was seeing quadruple with the mirage cover off. I recommended looking into one of these if you are shooting with a scope.

    Thank you TBAC and Silencer Shop for providing excellent customer service and great products!

    Also, I will be picking up a .338 ULTRA from TBAC when they are in stock.

    I heard about Thunder Beast's reputation for building the highest quality precision rifle suppressors through a good friend who shoots competitively. When I got my first precision rifle, Silencer Shop was taking orders for the newest line-up from Thunder Beast, the Ultra Series. So I ordered the Ultra CB9 for maximum suppression, and I couldn't be happier. The first thing I noticed about the Ultra CB9 was the superb fit and finish. The design is very sleek, and there are no visible flaws anywhere to be found. I was a little nervous about using a direct thread design, but my worries immediately disappeared when I threaded it onto the supplied Compact Brake. The can threads on smooth as butter and locks up rock solid on the tapered brake. The machining on this product is excellent, tolerances are tight, and I can tell Thunder Beast pays close attention to detail in their work.

    The performance of this can is absolutely incredible. I am running it on a 6.5 Creedmoor custom bolt rifle, and I get compliments on the suppressor every time I go to the range. Other shooters frequently start conversations with me by asking about the suppressor and expressing their amazement at how quiet it is. I can't help but share in their excitement, so I usually insist that they take a seat at my bench and put a couple rounds downrange through my rifle. They always get up with a smile on their face. The Ultra CB9 is very lightweight for a 9" can, and I don't notice the extra few ounces on the end of the barrel. The point of impact (POI) shift is minimal and repeatable: My suppressed groups impact about 1 MOA lower than my unsuppressed groups, with no shift in windage.

    Best use for this suppressor is on a bolt-action rifle, but is suitable for a semi-auto if you aren't slinging exorbitant amounts lead downrange for an extended period of time as this suppressor is not full-auto rated.

    The Thunder Beast Ultra CB9 has surpassed my expectations in every aspect, and I highly recommend this suppressor to anyone who is looking for a precision rifle suppressor. Thank you Thunder Beast for a great product, you have gained a customer for life. And thank you Silencer Shop for an easy purchasing process and great customer service and communication. Very much appreciated.

    I just shot through my new Ultra 9, very impressed how quiet my rifles were. Shot through a 308 semi auto, 7mm Rem Mag and a 300 Win Mag. Each rifle had little recoil and point of impact was easily seen. Suppressor weight does not change the balance of the rifles much. Flat dark earth color is very nice and these are quality builds. I would highly recommend these cans if you are in the market.
