The Otter Creek Labs Polonium-30 joins the Polonium family, including the Polonium and Polonium-K models. The Otter Creek Polonium is designed to last a lifetime and effectively protect your hearing across a wide range of calibers. Swap between your rifle-caliber platforms from short barrelled 5.56 to full-length 300 MAG with the confidence that it won’t only provide a quiet shooting experience but will stick with you through the harshest environmental conditions.
 
FEATURES & BENEFITS
The Polonium-30 is affordable, versatile, quiet, and durable. A minimalist ribbed profile provides extra surface area to boost heat dissipation and further fortify its 17-4 Stainless Steel construction. The Polonium 30 uses a 1.375x24 HUB mount that can accept any of your favorite mounting solutions, such as quick detach or direct thread adapters. The flash-hiding end cap minimizes flash signature, which is ideal for night hunting or low-light shooting.
