- Base interface
- 1/2x28 Direct Thread
This suppressor threads straight onto the barrel, so no mount is required. 10 mounts in our catalog are thread adapters that let it run on other barrel threads.

Check in the BuilderThe Thunder Beast Silencer Summit fires every suppressor entered on the same gun, with the same equipment. Caracal 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.
