The second-generation ULTRA 7 ("Gen2") superseded the original model on November 10th, 2020. The ULTRA 7 Gen2 is quieter and lighter than the original version. The official model ("ULTRA 7") does not change. Gen2 Ultra 7s can be identified by serial numbers that are higher than C40000 or by the visual changes.
The ULTRA 7 is our highly efficient compact precision rifle suppressor. It is best for applications where a compact form factor is important but excellent suppression is still required. The ULTRA 7 is available in .30 caliber and 6.5 mm caliber. The .30 caliber version is best for maximum flexibility for .223 up to .300 RUM. The 6.5 mm caliber version optimizes suppression performance on 6.5 mm and smaller calibers.
The .30 cal ULTRA 7 Gen2 meters at 139 dB (milspec left/right) and 129 dB at shooter’s-ear, shooting full-power (hot) M118LR ammunition from a 20″ AI AX. Compared to the original, the Gen2 is about 2 dB quieter at the muzzle and 2 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
The ULTRA Gen2 series represents a revolutionary improvement in titanium precision rifle suppressors. We took everything we've learned over the last 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.
