I recently purchased an older Clark Long Slide. It has a Bo-Mar rear sight with an adjustment that pushes down on the barrel when it returns to battery. Anyone know how to adjust this?

Is it the slide glide like this talks about ..
ACCURACY JOB WITH SLIDE GUIDE involves welding an extension to the front of the dust cover. The extension has two set screws. By adjusting the screws all horizontal and vertical movement of the slide is eliminated. The advantage of the slide guide method is that the slide is tight in the locked position but is free in the cycle mode. This enhances the functioning of the slide and eliminates break in period. Stainless pistols must use Slide Guide Method

No, it's not a slide guide. I have one of those on a Clark Pinmaster. This piece is part of the rear sight base that will press down on the rear of the barrel. Looks as though it's function is to tighten the lock up of the barrel. Maybe the slide too.

I can take a few pics, but will need some help to post. Or I can print them and send them to someone who could post. I'm not in my element on the computer.

Yep, it just looks like the 2 forward hex screws are the adjustment for for how much the barrel gets pushed down.

But i wonder what is the proper amount of tension so as not to torque the barrel to much

Good question. I would personally loosen it up and put it in battery. Then I would tighten the screws up until there was just no looseness/play in the barrel and try that.

Thanks for the help in posting the pictures Bud. I did call Clark and spoke to Renee and she said it is set when they build the pistol and don't mess with it. So I guess I don't mess with it. She also refered to it as a "tuner". An old timer gun smith told me you adjust the tuner by the way it groups. I guess...
Thanks to all,
tc

Will do Bud, but for now, I think I'll leave it alone. I want to work up some loads and will most likely begin with hard cast 200gr LSWCs. I have several boxes from my old Long Slide and even found some loaded rounds. If I remember, Bullseye and 231 ran about the best groups in that pistol. The only thing I didn't like about Bullseye was it burned so dirty.
