Otter Creek Labs Hydrogen S - Silencer 5/8X24 6.5 Black

The Otter Creek Labs Hydrogen S is an ultralight titanium suppressor engineered for hunters and precision shooters who refuse to compromise on weight or performance. Built from grade 5 titanium in a tubeless design, this 5/8x24 direct-thread silencer delivers serious sound reduction—137 dB on a 16" .308—while staying light enough for all-day carry on a hunting rifle or short-barrel setup. At just 9.3 ounces and 7 inches long, the Hydrogen S sheds heat faster than traditional suppressors, allowing you to keep shooting without thermal concerns on extended range sessions or in the field.

The Hydrogen S's distinctive external geometry isn't just for looks. Otter Creek Labs removed every gram of unnecessary material to keep the weight minimal while maintaining structural strength—the result is 10% more surface area than conventional designs in a lighter package. That extra surface area means faster cooling and more efficient heat dissipation, critical when you're running drills or pushing a short-barrel rifle hard. Full-auto rated, the Hydrogen S handles demanding use cases as long as you keep suppressor temperatures below 800 degrees.

Mounting flexibility is built in. The Hydrogen S ships with a direct-thread 5/8x24 adapter and includes a tube clamp for aftermarket mounting systems, so you can configure it to fit your rifle platform without adapters you don't need. Whether you're building an ultra-light hunting rig, running a 300 Blackout, or setting up a precision rifle for competition or range work, the Hydrogen S gives you the quiet and the weight savings in one package.
