Features
The Polonium is a rugged, duty-rated 5.56 suppressor designed for hard use, available in standard and K (short) lengths. For the best balance of size, weight, price, and sound suppression, the Polonium series is unmatched. Its real-world performance and track record speak for themselves—no inflated dB numbers or marketing hype needed.
The Polonium's 6mm bore is compatible with all 6mm/.243 cartridges. Its highly effective built-in flash hider significantly reduces muzzle flash, especially in low-light or night vision conditions. The distinctive design incorporates external weight reduction, strategically removing excess material without sacrificing strength. This results in a suppressor with 10% more surface area (depending on length), promoting faster heat dissipation and cooling.
Both the Polonium and Polonium-K utilize the industry-standard 1.375x24 rear thread, allowing compatibility with a wide range of mounting systems.
The Otter Creek Labs Polonium-K is a premium 5.56 duty suppressor built for a compact footprint. Made from H900 heat-treated 17-4 stainless steel, this 5.8-inch black silencer is full-auto rated and incredibly durable. Experience a smooth field experience with this rugged, tubeless powerhouse today.
At just 13.5 oz, the Polonium-K offers elite sound reduction while keeping your carbine agile. Its 1.375x24 HUB threads allow total mounting versatility on any 5.56 rig or 6mm host.
