Otter Creek Labs Polonium K 5.56 Suppressor, Flat Dark Earth

Otter Creek Labs Polonium K FDE Features and Performance

The Otter Creek Labs Polonium K FDE is a compact 5.56 suppressor built for shooters who want a hard-use rifle can without adding unnecessary length to the front of the gun. As the shorter K-length option in the Polonium line, it is well suited for carbines, shorter rifles, and practical setups where handling matters.

Built from 17-4 stainless steel and finished in Flat Dark Earth, the Polonium K is designed around durability and real-world rifle use. Otter Creek Labs positions the Polonium series as a duty-rated 5.56 suppressor line, and the K variant gives users a more compact option while retaining the rugged design that has made the series popular.

The Polonium K uses industry-standard 1.375×24 HUB rear threads, giving you flexibility when choosing a compatible mounting solution for your build. You can browse more
