Large "washer" shapes custom-cut from gasket material?

Or just stop using the rubbish Dual-Rail_Barrel attachment, which is the worst of them and appears to have been sent to manufacturing before the design was FINISHED. Not only does the rear locking ring tend to TURN, the front attachment sticks out too far and the front of the housing doesn't even have an indentation at the bottom for the rotation-lock button to snap into.
