The polonium-30 came about following the success of the Polonium and Polonium-K in 5.56


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. If you are after the best possible 5.56 performance the Polonium and Polonium-K in 5.56 both out perform the Polonium-30 when shooting a 5.56 rifle. But if you’re on a budget and looking for 1 suppressor you can switch around to all of your rifles and have respectable performance across all platforms with a mounting system of your choice the Polonium-30 can handle anything you can throw on it, guaranteed. 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 unique look comes from external weight reduction, removing all unnecessary material to keep the weight down but still as strong as possible – this results in a suppressor that has 10% more surface area and a lower weight that sheds heat faster and cools down quicker. The highly effective built in internal and external flash hider offer superior flash and signature reduction over the competition when using night vision.


The polonium-30 features industry standard universal 1.375×24 rear threads so you can pick what mounting system best fits your needs.
