Otter Creek Labs OPS/AE Past the Barrel Adapter Features The Otter Creek Labs P.T.B. Adapter is machined as a single piece from H900 heat treated 17-4 steel giving it the strength to handle the stress of repeated suppressor mounting and dismounting. Built specifically for the Ops Inc 12th Model AEM5 and OCM5 suppressors it solves a fitment problem that a standard over the barrel adapter cannot namely barrels with an outer diameter greater than 0.75 inch or less than 2.95 inches of exposed thread. Integrated wrench flats on the rear of the mount allow for easy installation or removal using any adjustable crescent wrench without needing a dedicated spanner tool. This design keeps the mounting process straightforward even on barrels with unusual geometry. Threading onto a standard 1/2x28 barrel this mount adds 2.90 inches to the overall system length once installed a figure worth accounting for when planning an overall suppressed setup. Because the mount places the end cap exit further from the muzzle than a standard mount Otter Creek Labs recommends checking alignment with a rod before firing to confirm the barrel threads are cut true. The gold finish distinguishes this adapter from other mounts in a suppressor collection while standing up to the raw heat treat process used in its construction. For shooters running an OPS/AE suppressor on a barrel that will not accept a standard mount this adapter is a purpose built fix for sale at GrabAGun.
