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) Mount (a "thread over muzzle brake" type 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, 6.5x47 Lapua, 6.5-284 Norma, and 7mm Remington Magnum & WSM.

The Ultras were designed to be the "ultimate" lightweight precision rifle suppressor. This means we used materials to meet those goals. Titanium, even Grade 5, is ultimately limited by temperature. The Ultras are very strong but excursions above 800 degrees are not good for the material. If you take it far enough above 1000 degrees, it will get too weak to sustain the blast and you would eventually get a failure. We recommend keeping the Ultra series less than 800 degrees.
Full auto by itself does not really increase the pressure or stress on the can, it's the heat energy input in combination. Full auto or bursts would be fine on an Ultra as long as the material temperature does not exceed that 800 degree safety mark. In our testing, one magazine fired rapid (mag-dump) from from an AR-10 or AR-15 does not exceed 800 degrees. Keep in mind this is firing at a full-auto-like rate. At that point you'd just have to let it cool. The second magazine may or may not cause it to exceed it depending on ambient conditions, loads, barrel length, etc. A shorter barrel will cause more heat input into the suppressor and its temperature will rise faster.
