The Polonium is a versatile 5.56 suppressor designed to deliver exceptional performance and durability. Whether on a mk18 or a DMR/SPR setup, this suppressor excels, providing the perfect balance between effectiveness and weight.

Its distinctive appearance is a result of strategic weight reduction, removing unnecessary material while retaining strength. With 10% more surface area, the Polonium dissipates heat rapidly, ensuring quicker cooldown times. Available in both standard and K configurations, the K version offers a slight tradeoff in noise level for reduced weight, shorter length, and lower back pressure.

Compatible with any 6mm/.243 cartridges, the Polonium features a 6mm bore. Its built-in internal and external flash hider effectively minimize flash and signature, offering superior performance when used with night vision. The suppressor boasts universal 1.375×24 rear threads, allowing you to select a mounting system tailored to your needs.
