The Polonium is a robust and versatile 5.56 suppressor, designed for quiet and durable performance. Whether it’s on a hard-hitting MK18 or a precision DMR/SPR setup, this suppressor excels in achieving optimal noise reduction. Its distinctive appearance stems from a focus on weight reduction, removing unnecessary material to maintain strength while reducing weight. As a result, the Polonium offers 10% more surface area, promoting quicker heat dissipation and faster cooldown.

Available in both standard and K configurations, the K version sacrifices a bit of sound suppression for advantages such as lighter weight, shorter length, and lower back pressure. The Polonium’s 6mm bore is compatible with any 6mm/.243 cartridges, ensuring versatility.

Its built-in internal and external flash hiders deliver exceptional flash and signature reduction, particularly when used with night vision equipment. The Polonium also features universal 1.375×24 rear threads, allowing you to select the mounting system that best suits your needs.
