The BOSS Chairman K is the shortened “kurtz” version of our unrivaled .30cal flagship silencer.  When size and form factor are the biggest driving factors but sound suppression is still critical, the Chairman K offers the best sound suppression of any 6″x 1.5″ silencer for your high-velocity, 7.62mm/308 long rifles.  The K version shines on subsonic 300 Blackout rigs, which is a great combination to an already short barrel.  The Chairman K uses the same Titanium tube and ultra-efficient stainless steel baffles as our other models, but the reduced length brings the weight down to just 12oz without a mount.  The titanium version is practically weightless.  

The Chairman K features our proprietary, Nikola Tesla-inspired, Coaxially-vented baffles that route the gasses through the silencer for a longer duration than in a standard baffle configuration, dramatically reducing the overall volume of the weapon when compared to other silencers of similar size. 

Includes a direct thread mount in 5/8 x24, but accepts any standard HUB 1.375-24 pattern mount, including SilencerCo ASR Bravo, or DeadAir Keymo, as examples.
