The CAT/DD/A1 (CAT “Dirty Dave” or CAT DD) is a compact “K-sized” 7.62x51mm NATO rifle silencer intended for use on reciprocating weapons. The silencer exhibits a high flow rate and significant sound suppression for its size. Using a high pressure adaptation of CAT SURGE BYPASS technology, the CAT DD produces low relative FRP and is one of the most consistent compact 30-caliber rifle silencers evaluated in the research pedigree in this combustion regime.

In this review, the CAT DD performance metrics depend upon suppressing a supersonic centerfire rifle cartridge; no easy task. How would the silencer perform on your .308 bolt-action rifle, and does it have performance traits that are appropriate for semiauto use?
