Rifle Scopes Acog/doctor optics question

Re: Acog/doctor optics question

This is what I got from page 13 of the Docter SightIII User Guide:

Replacing the battery
To replace the battery, the DOCTERsight is to be removed from the mounting plate.
The battery compartment is located at the bottom of the device. The exhausted
battery is taken out by putting the wrench key (or the screwdriver) onto the notch
located at the right bottom side. When the battery has been replaced, the sight is put
back onto the mounting plate and is fastened with the 2 countersunk screws. Due to
the precision positioning pins, a new shooting adjustment is not required.

Trigger Monkey's info about changing the battery is good, though I would disagree with the not needing to zero. I have changed a few of these in the past couple of years and each time it changed the zero.

There are two small screws, one on top and one on the side of the optic. These are set screws and need to be removed to access the actual adjustment screw. One turn equals 1 MOA.

I have only used the Docter on top of a ACOG and suggest a 25 yard zero. To zero with out taking all day and tons of ammo start out at 25 feet, do your gross adjustment there, keep in mind your POI will be about 4 inches lower than the POA. Once you feel like you are close to your desired zero then go back to 25 yards and verify.
