The same durability as the full size version, now with a smaller overall length.
The Otter Creek Labs Polonium K is made to be a quiet, duty rated, hard use, 5.56 suppressor in the K (Short) configuration. The Polonium K 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. Just like the Polonium, the Polonium K 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 K 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.
