OTTER CREEK LABS POLONIUM K

Description for Polonium and Polonium-K 5.56

The Polonium is made to be a quiet, duty rated, hard use 5.56 suppressor and is offered in both standard and K length options. If you’re looking for the best size, weight and price to sound performance ratio on the market that you can beat the absolute crap out of then look no further than the Polonium series. We don’t need to make up fake, fancy marketing language or give you padded/deflated dB numbers taken on subpar equipment – the reputation, performance and track record of the Polonium and Polonium-K speak for themselves.

The Polonium uses a 6mm bore that is also compatible with any 6mm/.243 cartridges and has a highly effective built in internal and external flash hider that offers superior flash reduction over the competition when using night vision or when shooting in low light conditions. 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 depending on the length that will shed heat and cool down quicker.

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

Description for Polonium-30

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. PSSST… I’ve got a dirty little secret other companies have been lying to you about for years to make a sale.. You do give up 5.56 performance when you go to a 30 caliber bore. The data is out there, the truth is out there, it just is what it is, any company that tells you their 30 caliber suppressor doesn’t experience this is lying to you and we just want to get that out in the open front and center. 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. I’d rather tell you that and lose a sale than you buy one and be disappointed based on a lie I sold you, that’s just who we are. 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.

*IMPORTANT NOTE* These are the listed barrel length restrictions for all of the Polonium series (Pol, Pol-K, Pol-30). You CANNOT shoot 6.5 or 7.62 projectiles through the 5.56 Polonium or Polonium-K. Meaning the 16” 300 win mag restriction applies to the polonium-30 and not the polonium 5.56 because you cannot shoot 300 win mag through the 5.56 suppressor. You would think something like that doesn’t need to be said but you’d be surprised.
