The Otter Creek Arms OCL-201 M4 Collar is a precision suppressor locating collar built for shooters who run serious sound reduction hardware on their rifles. If you're mounting an Ops Inc 12 Model, AEM5, or OCM5 suppressor to an M4 spec barrel, this collar is the hard-use interface that keeps everything aligned and secure shot after shot. It's the kind of component that doesn't get attention until you need it—and then you're glad it's there.
Built from H900 heat-treated 17-4 stainless steel, the OCL-201 is engineered for the durability that serious suppressors demand. The black nitride finish protects against corrosion and abuse while delivering the professional look you'd expect from Otter Creek Arms' no-nonsense engineering. This is suppressor hardware designed for precision rifles, tactical builds, and hunters who want rock-solid suppressor mounting without compromise.
Whether you're running precision rifle work at the range, hunting, or working a duty gun, a quality locating collar ensures your suppressor stays true to the barrel centerline. That consistency translates directly to performance and reliability. Otter Creek Arms built this collar to handle the real demands of suppressed rifles, not just look the part.
