Otter Creek Labs Polonium Suppressor

OTTER CREEK LABS POLONIUM: BUILT TO BEAT THE HEAT AND THE NOISEWhether 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.
