Hydrogen Series (K, S, L 6.5 & 7.62)

Hydrogen series – available in 6 different variations. L 7.62, L 6.5, S 7.62, S 6.5, K 7.62, K 6.5

The Hydrogen series are extremely light weight, extremely quiet suppressor made with the PRS shooters and hunters in mind. 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.

On a 20 pound match rifle, an ultra light hunting rig, short barrel 300 blk or your 5.56 running drills the Hydrogen series is right at home with a full auto rating so long as the suppressor is kept under 800 degrees.

All Hydrogen series suppressors feature industry standard universal 1.375×24 rear threads so you can pick what mounting system best fits your needs.
