The Griffin Armament Optimus is a modular, multi-caliber, 9mm bore centerfire rifle silencer that exhibits notably lower back pressure for its long length, with competitive sound signature reduction in the supersonic flow regime. The Optimus has been refined since its 2016 release; users should note that the supersonic suppression and back pressure characteristics of the Optimus highlighted in this review represent upper bound performance of the Optimus silencer on this host weapon platform.

In this review, the Optimus performance metrics depend upon suppressing a supersonic centerfire rifle cartridge; no easy task. How would the silencer perform on your .308 deer rifle?
