- Base interface
- 1/2x28 Direct Thread
This suppressor threads straight onto the barrel, so no mount is required. 6 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. Marmot 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.

- Crafted from 7075 aircraft-grade aluminum with a durable H-Series Cerakote finish, available in Black or Burnt Bronze.
- Fully serviceable — disassembles easily for cleaning and maintenance.
- Designed specifically for fixed and floating barrel 9mm and .22LR pistols, with no booster required on most models.
- Also performs great on 9mm and .22LR carbines and rifles.
- Includes 7 baffles plus both 9mm and .22LR end caps.
- Rated for use up to 500 degrees F.
- Function cannot be guaranteed on every pistol because of variables such as make, model, ammunition, slide weight and recoil spring tension; reduce the number of baffles if the pistol does not cycle reliably.
