OCL Hydrogen S: The Perfect Balance of Performance and Versatility
While the OCL Hydrogen S was designed as a mid-length, light suppressor with PRS shooters and hunters in mind, it’s so much more than you would expect. For its size, it’s exceptionally quiet. The balance of sound reduction, weight, and length is ideal for most applications. The “S” is well-rounded, being able to fill multiple roles without the sacrifices found in many suppressors.
For the mounting system, Otter Creek Labs includes a 5/8×24 direct thread mount with the Hydrogen S. Should the user prefer a different solution, the Hydrogen is threaded in 1.375×24 (Omega/Bravo/HUB), allowing for nearly any other mounting system to be installed in it. Direct thread, ASR, Key-Mo, Plan-B, Dual-Lok, and many more are possible.
Your heavy bolt-action rifle used for PRS matches will love it just as much as an ultralight hunting setup. While the initial design was around hunting and precision, the Hydrogen S shines just as brightly during drills on a 5.56 SBR or a short 300 Blackout for a relaxing day at the range.
Available in both 6.5 and 7.62 versions.
