AkMike, Merkel seemed reluctant to speak to me, perhaps since I am Canada (I called Merkel USA).

Chapuis, that might indeed seem plausible...but having both screws adjust the same barrel to match the other seemed equally plausible. With two choices of barrel aligned side-by-side, each of which needs adjustment in two different planes (vertical and horizontal) and two screws aligned over-and-under, it seemed like a reasonable question to ask.

Thanks anyway...I was able to get a copy of the Merkel regulation instructions from a poster on AR, and should be picking up the gun this week.
