Which ones fit your barrel and host?
Check in the BuilderThe Thunder Beast Silencer Summit fires every suppressor entered on the same gun, on the same day, with the same equipment. Chairman K was measured in 3 tests. Figures can only be compared with others from the same test, so each one links to everything else fired on that gun.

Manufacturer claim
- 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 8.9oz.
- Full-auto rated with no barrel-length restrictions, and factory serviceable.
- 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.
