This review details the Otter Creek OCM5, a 5.56 suppressor weighing 16 oz, designed as a lighter alternative to the Allen Engineering AEM5. It utilizes the Ops 12 mounting system for compatibility with Mk12 and similar platforms. Tested on an 18-inch barrel with PMC 55-grain ammo, the OCM5 achieved a significant 38.6 dB reduction, bringing the average sound level down to 127.8 dB, surpassing the AEM5's 131 dB. The suppressor is full-auto rated down to 10.3-inch barrels, made of stainless steel, and offers excellent flash suppression with minimal Point of Impact shift upon removal and reattachment.
