The Otter Creek Labs Polonium is a precision-built .30 caliber rifle suppressor engineered for shooters who demand exceptional durability, consistent sound suppression, and dependable performance under sustained firing conditions. Designed to handle .308 Winchester and 7.62mm cartridges, the Polonium excels in tactical, precision, hunting, and training applications.

Constructed from H900 heat-treated 17-4 stainless steel, the Polonium delivers outstanding resistance to heat, pressure, and erosion. This robust material choice allows the suppressor to maintain structural integrity during high-volume shooting while ensuring a long service life in demanding environments.

The suppressor features a 1.375x24 thread pattern and includes a 5/8x24 direct thread adapter, providing compatibility with most standard .30 caliber rifle barrels. Its direct-thread mounting system ensures a secure and straightforward attachment while maintaining excellent alignment and repeatable performance.

Finished in Flat Dark Earth Cerakote, the Polonium benefits from enhanced corrosion resistance and thermal stability while complementing modern rifle aesthetics. The Cerakote coating also adds an additional layer of protection against wear and environmental exposure, making it well suited for both field and range use.

Each Polonium suppressor is shipped with essential accessories to support proper installation and long-term maintenance. Included are a tube clamp for installing mounts and an instruction and specifications pamphlet to ensure correct setup and safe operation.
