Features
Designed for PRS shooters and hunters, the Hydrogen series of suppressors are exceptionally lightweight and quiet. Their distinctive appearance comes from strategic external weight reduction—removing excess material without sacrificing strength. This results in a suppressor with 10% more surface area and lower weight, leading to faster heat dissipation and cool-down.
Whether you're using a 20-pound match rifle, an ultralight hunting rig, a short-barreled 300 BLK, or a 5.56 for drills, the Hydrogen series is a perfect fit. It's even full-auto rated, provided the suppressor temperature remains below 800 degrees.
All Hydrogen series suppressors utilize the industry-standard 1.375x24 rear threads, allowing you to choose the ideal mounting system for your needs.
The Otter Creek Labs Hydrogen-K 6.5 is a featherweight masterpiece for hunters and PRS shooters. Built from Grade 5 titanium, this 5-inch, 6.7 oz silencer preserves your rifle’s natural balance. Its tubeless design sheds heat 10% faster, ensuring a smooth, consistent shooting experience in the field.
Optimized for 6.5 Creedmoor and 6mm ARC, the Hydrogen-K delivers a deep, pleasant tone with zero POI shift. The 1.375x24 HUB threads offer total mounting freedom, while the black Cerakote finish provides a clean look. Shop PSA for 2026’s best OCL deals and fast FFL shipping on this titanium powerhouse.
