I think one of my rear sights may have a dead spot. When I turn the windage knob It doesn't do anything for a few clicks and then when I turn it a few more clicks it moves the shot too far. Is their a simple way that I can test out the sight before spending 4-5 hundy on a new one?

Dial indicator?

Based on my back-of-the-napkin estimation, 1 MOA on a 30" sight radius is almost 0.009", so it would probably work, depending on the resolution of your clicks. It's probably not good enough to measure exactly, but should show motion or not.

You might need to get creative to mount it (probably remove the sight from the rifle and mount in a vice).

I never thought of using one of those. I have a few laying around the shop.

Thanks

Screw a sight riser block onto a steel flat plate. Mount the sight onto the sight riser and attach the DTI to the steel plate using the it's magnetic base.
Now you have a sight testing rig. Very easy to detect any backlash in your rear sight using the DTI.

I just clamp the sight in a vice with soft jaws and use a dialed indicator with a magnetic stand attached to the vice.

I can take a photo of the setup if you really need it.
