Description

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 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 features industry standard universal 1.375×24 rear threads, so you can pick what mounting system best fits your needs.

Made from H900 heat treated 17-4 stainless steel and constructed as a tubeless design, the specs are as followed:

  • Length: 5.8” (no mount)
  • Weight: 13.5 oz (no mount)
  • OD: 1.625”
  • 137 dB on 11.5” 5.56 SBR with BK 2209

Barrel length and firing schedule restrictions

  • 10.3” – 5.56/223
  • 11.5” – 6 ARC
  • 14.5” – 6 Creedmoor, 6 dasher, 243 Winchester and other 6mm cartridges.
  • Full auto rated – no BS.

We do however discourage 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 – even on suppressors that aren’t ours, we still recommend this.

What’s included in the box?

  • Suppressor
  • OCL Stickers
  • Instruction and specs pamphlet
  • 1/2×28 direct thread adapter
  • Tube clamp for installing mounts
