Product Code: POL556 UPC/Barcode: 10080607

The polonium is made to be a quiet, duty rated, hard use, 5.56 suppressor. 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 unique look comes from external weight reduction, removing all unnecessary material to keep the weight down but still as strong as possible – this results in a suppressor that has 10% more surface area and a lower weight that sheds heat faster and cools down quicker. 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 features industry standard universal 1.375×24 rear threads so you can pick what mounting system best fits your needs.
