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 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)
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.
