Otter Creek Labs OCM5

The Otter Creek Labs OCM5 is a modernized evolution of the classic OPS/Allen Engineering AEM5 suppressor, built for today’s precision shooters who demand superior sound suppression, minimal blowback, and rugged durability. Designed to preserve the proven performance of the AEM5 while integrating advanced manufacturing improvements, the OCM5 delivers unmatched repeatability and reliability.

Constructed from H900 heat-treated 17-4 stainless steel, the OCM5 offers exceptional strength and heat resistance. Its optimized internal geometry reduces gas blowback and carbon buildup while maintaining the legendary tone and precision that the original AEM5 series was known for.

The OCM5 is designed to work seamlessly with AEM5/OPS-style mounts and collars, allowing compatibility with rifles already configured for those systems. It provides outstanding sound suppression on 5.56 NATO and .223 Remington platforms, including precision rifles and AR-15 variants.
