Check in the BuilderThe Thunder Beast Silencer Summit fires every suppressor entered on the same gun, with the same equipment. Speakeasy 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 Speakeasy keeps things straightforward with a simple baffle design —and somehow still ends up quieter than your favorite .30 cal can .
- Just impressed, honestly.
- You can run it hard, not think about it much, and keep doing that for a long time.
- And then there’s subsonic .300 BLK.

- Yeah… this thing is quiet .
- Like, quietest you’ve ever heard quiet.
- It’s called the Speakeasy because it keeps things low-key.
- It works because everything else lines up the way it should.
- Think of this as the Steel Full Nelson that decided to ride on a Quickie Mount .
- It’s all steel , which means no flash and a whole lot of durability.
- Steel also lets us build it more efficiently, which means it ends up being more affordable for you .
- One more fun detail — even though it’s steel, it actually weighs less than the Full Nelson in titanium .
