Otter Creek Labs Polonium K: Big Performance in a Short Package
If you're running drills, shooting under NODs, or stalking hogs at last light, the Polonium K brings serious performance without adding unnecessary length. At just 4.8 inches, this 5.56K suppressor delivers top-tier sound and flash reduction in a lightweight, hard-use design.
Crafted from 17-4 stainless steel and rated for full-auto use, the Polonium K handles high-volume fire without hesitation. Its erosion-resistant baffle design and 6mm bore make it equally capable on 6 ARC, 6mm Creed, or your favorite .223 rifle. Gas management is improved, too—fewer fumes in your face when you're behind the gun.
An integrated flash hider cuts your visible signature in low light, while HUB-compatible 1.375x24 rear threads let you choose your preferred mounting setup. Whether you're using the included 1/2x28 direct thread or swapping in a QD system, the Polonium K adapts fast.
