Otter Creek Labs
The Otter Creek Labs Hydrogen L is an ultra-lightweight titanium suppressor built for hunters, precision shooters, and anyone who refuses to compromise between sound reduction and weight savings. Machined from grade 5 titanium in a tubeless design, the Hydrogen L delivers serious noise reduction—130 dB on a 16" .308 with BK 2209 powder—while tipping the scales at just 11.9 ounces. For a full auto-rated suppressor, that's a remarkable combination of durability and portability.
The Hydrogen L's distinctive profile comes from Otter Creek Labs' commitment to purposeful weight reduction. Rather than unnecessary bulk, every design choice prioritizes strength and efficient heat shedding. That means faster cool-down cycles and a suppressor equally at home on a precision match rifle, a lightweight hunting build, or short-barrel platforms like the 300 Blackout. The 1.625" outer diameter and 9" length give you a balanced profile without adding heft to the gun.
Threading and mounting flexibility come standard: the suppressor ships with a 5/8"×24 direct-thread adapter and a tube clamp, so you can integrate your preferred mounting system. Industry-standard 1.375"×24 rear threads mean you're not locked into proprietary hardware down the road. It's the kind of practical thinking that separates a tool from a gimmick.
Whether you're running precision drills, hunting at distance, or building an ultralight rig, the Hydrogen L proves that effective suppressors don't need to be heavy. Included in the box: the suppressor, 5/8"×24 adapter, tube clamp, stickers, and instruction/specs pamphlet.
| Length (no mount) | 9 inches |
| Weight (no mount) | 11.9 oz |
| Outer Diameter | 1.625 inches |
| Material | Grade 5 titanium |
| Design | Tubeless |
| Front Threads | 5/8"×24 |
| Rear Threads | 1.375"×24 (universal) |
| Sound Reduction | 130 dB (16" .308, BK 2209) |
| Full Auto Rating | Yes (keep under 800°F) |
| What's Included | Suppressor, 5/8"×24 direct-thread adapter, tube clamp, stickers, instruction/specs pamphlet |
The Hydrogen L ships with a 5/8"×24 direct-thread adapter for immediate installation. The rear features industry-standard 1.375"×24 threads, so you can swap mounting systems without replacing the suppressor. A tube clamp is also included to help secure alternative mounts.
Yes, the Hydrogen L carries a full-auto rating. Keep the suppressor temperature under 800°F during sustained fire to maintain that rating and ensure longevity.
At 11.9 oz without the mount, the Hydrogen L is one of the lightest suppressors in its class. On a lightweight hunting rifle or ultralight match build, that's a negligible impact on balance and handling.
The Hydrogen L is threaded for 5/8"×24 adapters. Confirm your rifle's specific thread pitch before ordering. The suppressor's performance on platforms like .308, 5.56, and 300 Blackout is documented; other calibers should be verified for compatibility with the 5/8"×24 standard.
