7mm Backcountry, 18" bolt-action rifle2026

2 suppressors were fired on this same gun, with the same ammunition. It was never fired without a suppressor, so how much quieter each one made it cannot be worked out. The figures below are the level measured with the suppressor fitted.

Products come and go from these events voluntarily. A suppressor missing from this list was not tested, nothing more. Names are shown as Thunder Beast listed them. A name without a link doesn’t have a page on Baffled yet. Differences smaller than 2.52 dB are closer than this test can reliably measure. The results also don’t record which mount or muzzle device each suppressor was fitted with, and that hardware can affect both the reading and the weight and length shown above. Decibels are not a count of anything: as a rule of thumb every 10 dB is roughly a halving of how loud something seems, so the gaps here are larger than they look.

Every row opens to show all three microphones, and it is worth opening. A suppressor can be the quietest here beside the muzzle and middling at the shooter’s ear, so a claim about one says nothing about the other.

Thunder Beast published the decibel figures, the weights and the lengths. The resolution limit of 2.52 dB, the shaded band are worked out here from those measurements.
