The OCL OPS/AE O.T.B. Adapter is a one-piece over-the-barrel mounting solution designed for shooters running Ops Inc 12th model AEM5 and OCM5 suppressors. Built from H900 heat-treated 17-4 stainless steel, this raw-finish adapter bridges your suppressor to any 1/2×28 threaded barrel measuring 0.75" OD or smaller, making it a versatile choice for precision rifles, hunting guns, and tactical builds where barrel length and geometry allow. The integrated wrench flats machined into the rear let you index and remove the adapter cleanly with a standard adjustable crescent wrench—no proprietary tools required.
Over-the-barrel mounting is valued for its rigidity and simplified timing when you're threading a suppressor onto a crowded action or when you want the silencer positioned close to the muzzle for minimal impact on sight lines. The H900 steel offers excellent corrosion resistance and strength under the pressures of suppressed fire, and the raw heat-treated finish will develop character over time while resisting rust in field use.
Before ordering, confirm your barrel has at least 2.95 inches of exposed threads forward of the action—a quick measurement at the bench saves frustration. If your barrel is heavier than 0.75" OD or threads differ from 1/2×28, this adapter won't fit; verify your setup first. This is a precision accessory for a precision job; measure twice, mount once.

The OCL OPS/AE O.T.B. Adapter is designed for Ops Inc 12th model AEM5 and OCM5 suppressors only.
This adapter requires a barrel with 1/2×28 threads, a maximum OD of 0.75", and at least 2.95 inches of exposed barrel between the muzzle and the action. Measure your barrel crown-to-action distance before purchasing to confirm fit.
No. The adapter has integrated wrench flats on the rear that work with any standard adjustable crescent wrench for quick installation and removal. No proprietary wrenches are needed.
Over-the-barrel mounting provides a rigid connection between your suppressor and barrel, locks the silencer in precise timing for optimal sound reduction, and keeps the suppressor positioned close to the muzzle for minimal sight-line obstruction.
