Staff was super friendly and just as knowledgeable! Pricing is beyond reasonable in the best way possible not to mention they had items in stock that NO ONE else had. They made the 4473 process an absolute breeze. I’ll definitely be coming back for more of the goods.

Otter Creek Labs Polonium 5.56

Store/Suppressors

Product Details

The Polonium is made to be a quiet, duty-rated, hard-use, 5.56 suppressor. Just as much at home on an MK18 getting hammered with heavy strings of fire as it is on a DMR/SPR setup where ultimate suppression is the goal.
The Polonium uses a 6mm bore that is compatible with any 6mm/.243 cartridges.
The highly effective built-in internal and external flash hider offers superior flash and signature reduction over the competition when using night vision.
The Polonium features industry-standard universal 1.375×24 rear threads, so you can pick the mounting system that best fits your needs.

Made from H900 heat-treated 17-4 stainless steel and constructed as a tubeless design, the specs are as follows:
Length: 5.8” (no mount)
Weight: 13.5 oz (no mount)
OD: 1.625”
