The Polonium is offered in both standard and K variants and is a quiet, duty rated, hard use 5.56 suppressor. The Polonium K is slightly louder but is lighter, shorter and lower back pressure attributes.
The unique design is due to the external weight reduction, removing all unnecessary material without sacrificing strength. The result is a 10% more surface area and lower weight for faster heat dissipation.
The Polonium uses a 6mm bore and is compatible with 6mm/.243 cartridges. An integrated internal and external flash hider offers superior signature reduction when using night vision. The Polonium uses the industry standard 1.375x24 rear threads for various mounting systems.

*IMPORTANT NOTE* These are the listed barrel length restrictions for all of the Polonium series (Pol, Pol-K, Pol-30). You CANNOT shoot 6.5 or 7.62 projectiles through the 5.56 Polonium or Polonium-K. Meaning the 16” 300 win mag restriction applies to the polonium-30 and not the polonium 5.56 because you cannot shoot 300 win mag through the 5.56 suppressor. You would think something like that doesn’t need to be said but you’d be surprised.
