Otter Creek Labs Polonium-30 Suppressor

Otter Creek Labs Polonium-30 – Durable, Multi-Caliber Suppression

The Otter Creek Labs Polonium-30 expands the Polonium lineup to cover 5.56 through .300 Norma Magnum. With a robust 17-4 stainless steel body and a flash-hiding end cap, this multi-caliber suppressor excels in both low-light conditions and high-volume shooting.

Featuring a 1.375×24 HUB mount, the Polonium-30 offers mounting flexibility—use your preferred QD or direct-thread solution. Rated for full-auto firing schedules, it’s built to handle the harshest environments and firing conditions, ensuring reliable performance on every shot.
