Default Suggestions for M1A Scope

I read in the American Rifleman scopes with fixed power to 4.5 will be allowed in CMP and NRA High Power competition. Any suggestions?

Night Force or March if you can afford it. Otherwise, Vortex or Leopold.
If you check out the National Match Forum, Leupold was doing well in the polls until people started have repeatability issues. Dialing from 600 to 300 yards, 1-2 MOA errors for a few shots then the erector tube pops into the correct position and you're on target. Vortex has been more reliable.

The problem with most scopes is the leaf springs that act on the erector tube. They typically apply 2-3 pounds of pressure whereas the higher end scopes or the Burris with the coil springs apply closer to 10 pounds of pressure.

With any scope, when you initially start to use it, run the adjustments stop-to-stop at least twice. Then find the mechanical center and go from there.

Another trick is to always approach your adjustment point dialing the adjustment screw to the right, moving the erector tube into the spring. It's going the other way most folks have seen the errors.
