Anybody have a photo, or a diagram of the adjustment gadget on the Merkel double rifles?? Can't picture how the muzzles move, but a rib still connects them.

The adjustments are not visible except for the Allen wrench holes. The left barrel is not connected to the rib (at the muzzle, anyway).

Thanks! Looks like the allen screws probably have cone shape ends, and are bored at an angle, so that the top screw moves the left barrel down/left, and the bottom screw moves the left barrel up and left, when screwed in. I can get allen set screws with the little nylon lock insert, so it won't vibrate out of regulation from recoil. Building my own...on a Merkel 12 ga. action.
