M40 A1 scopes with cam

[EvanDaniels]

Does anyone remember in the early 2000’s Unertl (or maybe it was leupold) had scopes with a cam adjustment built into the turret. Similar to the rear sight adjustment on the M16 with 100m detents.

I think IBA had these on M40 clones in that time period as well.

Where to find info/ history of these?

IIRC, they were made by Leatherwood and were called ART (Automatic Ranging Telescope) scopes. You can Google for the history.

That looks like it accomplished the same thing but the one I’m talking about was integrated into the turret.

I never knew of a scope where the cams were in the turret. Let us know if you find out.

Maybe @buffalowinter can shed some light. He is the master in this area.

I’ve tried finding it, but nothing. Maybe I’m wrong. I don’t know.

Do you mean the standard Unertl MST-100 that was used on the M40A1? Had elevation stops for 100-1000yds and a +/- 3moa in 1/2 moa fine tune knob, windage with 4 1/2 or 8 moa adjustment.

The MST-150 was the .50 cal version that had stops out to 1800yds.
