Following up yesterday’s range trip, I needed to reset the scope. The AR 10 works pretty hard, and has loosened up other things, and scope mounts are no exception.
I got the rifle out on the work bench and only 2 of the 8 machine screws were tight. When I loosened them up a turn, the scope moved freely back and forth. Of course, it rotated freely, too.

This is where the right tools make a critical job much easier. First, you need to make sure the entire rifle is level.

once the body of the rifle is level, you use the clamp on-level on the barrel as the reference point. The movable level then goes up to the flat turret top. As you then tighten the machine screws (alternating sides is best), you can see the effect on the level of the scope. The goal is to tighten up the screws to the proper torque, all while maintaining a level condition. The Wheeler leveling tool really simplifies the process.

Another way is to use angled leveling shims between the rail and a flat bottom surface of the scope. That works well IF you can find clearance and a flat spot.

The next great tool is a torque screwdriver. Most all scope manufacturers tell you the specific torque to use – it usually runs between 18 and 24 inch-pounds. NOT foot-pounds! Fat Wrench makes a great one with an easy-to-see and use torque gauge, and lots of bits for various screw heads and sizes.

Both tools come in compact and sturdy containers that fit easily into a range bag.

I’ve had many a time on the range when someone needs those tools; otherwise, their range time just came to an end.
It’s nice to be able to help out. And it also impresses the Range Babes.
