The Otter Creek Labs Polonium 30 is a short, tough .30 caliber suppressor built from H900 17-4 stainless steel. At about 5.8" it keeps your rifle compact, and the standard 1.375x24 HUB rear thread means you can run it direct-thread or on almost any HUB quick-attach mount.

- Short: about 5.8"
- H900 17-4 stainless steel
- Direct thread or 1.375x24 HUB mounts
