Otter Creek Labs OCM6 — 6mm Bore Suppressor

Otter Creek Labs OCM6 Suppressor 6mm Bore - Black

Get genuine second-generation suppressor engineering with real multi-caliber flexibility — the Otter Creek Labs OCM6 is a 6mm bore OPS/AE pattern suppressor built from titanium and Inconel, designed to extend well beyond standard 5.56 applications.

As the evolution of the proven OCM5, the OCM6 combines a machined titanium outer tube with a 3D-printed 718 Inconel core, keeping weight genuinely low while delivering real durability and erosion resistance for demanding, high-round-count use. That 6mm bore is a genuine functional upgrade: it maintains full compatibility with .223/5.56 while expanding to handle a wide range of 6mm cartridges, including 6 ARC, 6 Dasher, 6 Creedmoor, and .243 Winchester — a single suppressor that covers significantly more of your rifle lineup than a dedicated 5.56-only can.

Otter Creek Labs engineered the OCM6 specifically to improve the shooter's experience over previous OPS/AE-pattern suppressors, reducing backpressure and port pop for a genuinely more pleasant shooting experience. It maintains compatibility with existing OPS 12/AEM5 mounting systems, making it a natural fit for MK12, Gordon-style, and other precision builds where you're already invested in that mounting ecosystem. At 8.8" in length, 1.5" O.D., and 16.02 oz, it stays genuinely manageable despite the expanded caliber coverage.

Whether you're running multiple rifles across 5.56 and various 6mm cartridges and want one suppressor to cover them all, upgrading from an OCM5 for genuinely reduced backpressure, or building a precision rig around the established OPS 12/AEM5 mounting system, the OCM6 delivers real multi-caliber engineering without compromising durability.
