Ultra 9CB Gen 2

The second-generation ULTRA 9 (“Gen2”) superseded the original model on November 10th, 2020. The ULTRA 9 Gen2 is quieter and lighter than the original version. The official model (“ULTRA 9″) does not change. Gen2 Ultra 9s can be identified by serial numbers that are higher than C40000 or by the visual changes.

The ULTRA 9 is our full-size precision rifle suppressor. It is best for applications where maximum suppression is key. The ULTRA 9 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 9 Gen2 meters at 135 dB (milspec left/right) and 123 dB at shooter’s-ear1, 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 5 dB quieter at the shooter’s ear.

The 6.5 mm cal ULTRA 9 Gen2 meters at 131 dB (milspec left/right) and 121 dB at shooter’s-ear1, shooting Hornady 140gr ammunition from a 24″ AI AX. Compared to the original 6.5 mm version, the Gen2 is about 2 dB quieter at the muzzle and 2 dB quieter at the shooter’s ear.

The ULTRA 9 Gen2 weighs 10.0 ounces (1.9 ounces lighter than the Gen1).
