Otter Creek Labs Polonium K 5.56mm Direct Thread Suppressor

The Otter Creek Labs Polonium K is the short version of OCL's duty rated 5.56 can. Next to the standard Polonium it gives up a little sound suppression, but it is shorter, lighter and runs lower back pressure. It is 4.8" long, 1.625" in diameter and weighs 11.5 oz without a mount. The bore is 6mm, so it also takes 6mm and 243 cartridges.

A built in flash hider inside and outside the can keeps signature down under night vision. The cut outer profile removes weight and adds surface area, so it sheds heat faster. It is a welded tubeless design in heat treated stainless steel, full auto rated. The rear uses universal 1.375-24 threads; a 1/2-28 direct thread adapter and a tube clamp for changing mounts are included.
