Otter Creek Labs Polonium K 5.56 Suppressor, Black

Otter Creek Labs Polonium K 5.56 Suppressor Features and Performance

The Otter Creek Labs Polonium K 5.56 Suppressor is built for shooters who want a compact, durable rifle suppressor that still delivers serious hard-use performance. Designed as the shorter K-length option in the Polonium series, it keeps overall length down while maintaining the rugged construction and practical performance that Otter Creek Labs is known for.

Built from H900 heat-treated 17-4 stainless steel, the Polonium K is made for demanding 5.56 setups, including rifles where durability, reduced added length, and solid real-world usability matter more than oversized dimensions. Its compact footprint makes it a great fit for carbines, shorter rifles, and other setups where handling is a priority.

The suppressor uses industry-standard 1.375×24 HUB rear threads, giving users flexibility when choosing compatible mounting solutions. If you are building out a complete setup, you can browse more
