Made for the person who is on a budget and just wants 1 suppressor to change around on all of their rifles this suppressor follows the same design goals of every product we make – good, durable, affordable suppressors for the working man that punch above their price point. From a full auto short barrel 5.56 rifle, 300 blackout, 308 all the way up to the big daddy 300 RUM and 300 Norma magnum. 

The Polonium is made to be a quiet, duty rated, hard use, 5.56 suppressor. Just as much at home on a MK18 getting hammered with heavy strings of fire as it is on a DMR/SPR set up 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 offer superior flash and signature reduction over the competition when using night vision.
Compatible with 1.375 x 24 HUB mounts. 

When YHM engineers set out to make a suppressor, they look far beyond that of just making the designated caliber quieter. They make it work across the board so that you, the shooter, can enjoy versatility across your entire arsenal all at a budget friendly price while maintaining that rugged durability you’ve come to expect from YHM®. The primary goal was a 9mm suppressor capable of handling high volumes of fire and the ability to run other calibers such as .300 BLK and .308 Win.
