The Otter Creek Labs OCM5 is OCL's 5.56 take on the OPS Inc 12th Model / AEM5 over-the-barrel suppressor: the classic MK12 and SPR look, with the can reflexed back over the barrel so it adds much less length than it measures. It uses the same OPS/AE mounting system as the originals, so OPS 12 and AEM5 mounts, collars and muzzle devices work with it.
The OCM5 has since been replaced by the 6mm-bore OCM6, which is lighter and runs with far less back pressure. If you want the exact OCM5 for a period-correct build, or already have the mounts, this is it. Made in London, Kentucky, with a lifetime warranty.
