Check in the BuilderThe Thunder Beast Silencer Summit fires every suppressor entered on the same gun, on the same day, with the same equipment. Biscuit-S 5.56 was measured in 1 test. Figures can only be compared with others from the same test, so each one links to everything else fired on that gun.

Manufacturer claim
- Decibel rating: ears 145-146db, muzzle 151db.
- 100% laser welded tubeless baffle stack; the Biscuit line is fully welded and the exit caps are not removable.
- Industry-standard 1-3/8x24 threaded HUB, so shooters can keep their existing muzzle devices and use a wide variety of Abel Company adapters.
- Design goals: reduce dB to a manageable level (~140), mitigate back-pressure via a higher flow rate, minimize or eliminate POI shift, and keep length short.
