Otter Creek Labs Polonium Suppressor

Whether you’re blasting through a training day or tightening groups at distance, the Otter Creek Labs Polonium is your go-to 5.56 suppressor. Designed as the everyman’s workhorse, it delivers proven decibel reduction with full-auto durability and smart design touches that punch above its price point.

Machined from 17-4 stainless steel, the Polonium runs a ribbed external profile that increases surface area for faster cooling under pressure. An integrated flash hider reduces your visible signature when you’re running under NODs or in low light. The rear end is threaded 1.375×24 HUB to accept your favorite HUB-mount system or direct-thread setup.

FEATURES & BENEFITS

The central advantage of the Polonium is it’s incredibly durable construction. The minimalist front-ribbed profile provides 10% extra surface area for additional heat dissipation, keeping your shooting experience comfortable and consistent. Its internal/external flash hider reduces your flash signature which is particularly nice for night hunting or shooting under low light. With its universal 1.375×24 HUB mount rear threads, the Otter Creek Labs Polonium suppressor adapts to your choice of mount.
