Otter Creek Labs Polonium 5.56 Suppressor - FDE

Dominate high-volume tactical courses and long-range precision setups with the Otter Creek Labs Polonium 5.56 Suppressor in Flat Dark Earth (FDE). Engineered as a whisper-quiet, duty-rated, hard-use silencer, the Polonium is equally at home getting hammered with rapid strings of fire on a Mk18 SBR as it is providing maximum sound mitigation on a DMR or SPR precision build. Precision-machined from H900 heat-treated 17-4 stainless steel with a tubeless construction and finished in a high-temp FDE Cerakote, this suppressor is built to handle heavy operational schedules without flinching.

Featuring a 6mm bore diameter, the Polonium seamlessly supports 5.56 NATO / .223 Rem alongside 6mm ARC, 6mm Creedmoor, and .243 Win cartridges. Its built-in internal and external flash hider geometry delivers superior flash and signature reduction for night vision operations, keeping visual bloom to an absolute minimum. Equipped with industry-standard universal 1.375x24 HUB rear threads, an included 1/2x28 direct thread mount, and a specialized tube clamp for effortless mounting installation, the Polonium provides world-class suppression in a compact 5.8-inch footprint.
