A hard use suppressor that is easy on your bank account.


The Otter Creek Labs Polonium is made to be a quiet, duty rated, hard use, 5.56 suppressor. The Polonium is just as much at home on a MK18 getting hammered with heavy strings of fire as it is on a DMR/SPR set up where ultimate suppression is the goal. The Polonium uses a 6MM bore that is compatible with any 6MM/.243 cartridges. The highly effective built in internal and external flash hider offer superior flash and signature reduction over the competition when using night vision. The Polonium also features industry standard universal 1.375-24 rear threads so you can pick what mounting system best fits your needs.

Otter Creek Labs discourages the use of pronged flash hiders such as the Deadair 3 prong, and SOLGW nox on barrels shorter than 12.5 inches. Pronged flash hiders do speed up wear on ANY suppressor. This is just simply a recommendation, not a requirement.
