Otter Creek Labs Polonium 30 7.62 Suppressor Flat Dark Earth

Otter Creek Labs Polonium 30 7.62 Suppressor Flat Dark Earth

The Otter Creek Labs Polonium 30 is a hard-use, duty-rated 7.62mm suppressor engineered for shooters who prioritize sound suppression, durability, and mounting flexibility. Constructed from H900 heat-treated 17-4 stainless steel, the Polonium 30 is built to withstand demanding firing schedules while maintaining a relatively compact 5.8-inch length and 13.5-ounce weight.

Equally at home on a hard-running semi-automatic rifle or a precision-oriented DMR/SPR setup, the Polonium 30 combines full-auto-rated construction with an innovative exterior profile designed to remove unnecessary material, increase surface area, and improve heat dissipation. Industry-standard 1.375x24 HUB-compatible rear threads also give shooters the freedom to configure the suppressor with their preferred compatible mounting system.

Built for Hard Use

Otter Creek Labs designed the Polonium 30 as a quiet, duty-rated, hard-use suppressor. Its H900 heat-treated 17-4 stainless steel construction provides the durability required for demanding rifle applications and heavy firing schedules.

The suppressor is full-auto rated, making it suitable for high-volume use on compatible host firearms while maintaining the rugged construction expected from the Polonium series.

H900 Heat-Treated 17-4 Stainless Steel

The Polonium 30 is manufactured from 17-4 PH stainless steel with an H900 heat treatment. This material and heat-treatment combination provides the strength and durability needed for a suppressor designed around demanding duty use.

Weight-Reducing Exterior Design

The distinctive exterior profile of the Polonium 30 is functional as well as recognizable. Otter Creek Labs removes unnecessary external material to reduce weight while retaining strength.

This design also creates approximately 10% more external surface area, allowing the suppressor to shed heat and cool more efficiently after firing.

Integrated Flash Reduction

The Polonium 30 incorporates internal and external flash-hiding features designed to reduce visible muzzle flash and overall firing signature. This is particularly beneficial during low-light shooting and when using night vision equipment.

HUB-Compatible Mounting

The rear of the Polonium 30 uses industry-standard 1.375x24 HUB threads. This provides broad mounting flexibility and allows the suppressor to accept a variety of compatible HUB mounting systems.

This configuration includes a 5/8x24 direct thread adapter along with a tube clamp for installing mounts, giving shooters a straightforward mounting option while retaining the ability to change to another compatible HUB system.
