The previous Sound Signature Reviews, up to and including Review 6.16, have featured various silencers on several host weapons. Eight of those reviews feature centerfire rifle silencers; two of which were tested in two configurations each due to modularity of the silencer body or end-cap. This is a comparative summary of the objective performance of those ten total configurations.

This Results Summary is part of ongoing PEW Science small arm weapon system sound signature research.

The data herein references the Suppression Rating and relative back pressure metrics which have been reported throughout the centerfire rifle reviews, to date, in order to frame objective flow rate characteristics of the silencers for their prospective use on semi- and fully-automatic small arms. This data is the first of its kind in the public domain and represents a direct contribution of PEW Science member-funded research to the state of practice.
