OCL Short Spring Locating Collar - Black

The OCL Short Spring Locating Collar in black is a precision suppressor accessory engineered for shooters running Ops Inc 12, AEM5, or OCM5 cans. This locating collar handles the mechanical work of positioning your suppressor consistently on the host barrel—critical for accuracy, sound signature, and day-to-day reliability. Built from H900 heat-treated 17-4 stainless steel and finished in black nitride, it's built to last through countless attachment cycles without wear or corrosion compromising function.

If you're running a short-barreled rifle, pistol-caliber carbine, or any setup where a compact suppressor mount matters, this collar ensures your can seats the same way every time. The short profile keeps overall length down while delivering the rigid locating support that quality suppressors demand. Black nitride finish resists wear and blends with modern tactical setups.

Suppressors are only as good as their mounting hardware. A worn or sloppy collar costs you consistency and can invite copper fouling and POI shift. The OCL collar is a straightforward, no-fuss upgrade or replacement that restores that rock-solid seat—exactly what Otter Creek Labs builds for.
