Thunder Beast Ultra 5 Gen 2 Suppressor .30 Caliber CB Mount

Affectionately called the “Baby Beast” by some users!

The second-generation ULTRA 5 (“Gen2”) superseded the original model on November 10th, 2020. The ULTRA 5 Gen2 is quieter and lighter than the original version. The official model (“ULTRA 5”) does not change. Gen2 Ultra 5s can be identified by serial numbers that are higher than C40000 or by the visual changes.

The ULTRA 5 is our super compact .30 caliber precision rifle suppressor. It is best for applications where minimum size is the highest priority but good suppression is still required.

The .30 cal ULTRA 5 Gen2 meters at 145 dB (milspec left/right) and 133 dB at shooter’s-ear¹, shooting full-power (hot) M118LR ammunition from a 20″ AI AX. Compared to the original, the Gen2 is about 4 dB quieter at the muzzle and 3 dB quieter at the shooter’s ear.

The 6.5 mm cal ULTRA 5 Gen2 meters at 142 dB (milspec left/right) and 130 dB at shooter’s-ear¹, shooting Hornady 140 gr ammunition from a 24″ AI AX.. Compared to the original, the Gen2 is about 1 dB quieter at the muzzle and 1 dB quieter at the shooter’s ear.

We now specify the dB rating as a single number due to the long-term consistency of the B&K PULSE system. These should be considered the “reference” numbers compared to anything published previously — please see our youtube videos.

The ULTRA 5 Gen2 weighs 6.0 ounces (1.6 ounces lighter than the Gen1).
