Otter Creek Polonium K 556 Rifle Suppressor - Black

The Polonium is made to be a quiet, duty rated, hard use 5.56mm suppressor. If you're looking for the best size, weight, and price to sound performance ratio on the market that you can beat the absolute crap out of, then look no further than the Polonium Series. Otter Creek Labs doesn't need to make up fake, fancy marketing language or give you padded/deflated dB numbers taken on subpar equipment; their reputation, performance, and track record of the Polonium series speaks for themselves.The Polonium uses a 6mm bore that is also compatible with any 6mm/.243 cartridges and has a highly effective built in internal and external flash hider that offers superior flash reduction over the competition when using night vision or when shooting in low light conditions. 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 depending on the length that will shed heat and cool down quicker. The Polonium-K features industry standard universal 1.375"x24 rear threads so you can pick what mounting system best fits your needs.Specifications:H900 Heat Treated 17-4 Stainless SteelConstructed as a CNC Welded Tubeless DesignLength: 4.8"Weight: 11.5 oz w/ No MountDiameter: 1.625"Barrel Length Restrictions:7.5" - 5.56mm/.223Rem and 7.62x39mm10.5" - 6 ARC12.5" - 6mm Creedmoor and .243 WinchesterFull-Auto Rated: No B.S.
