Scope for ar used in competion - Vortex Golden Eagle 15-60x52mm 30mm Tube Second Focal Plane Rifle Scope

I purchased this scope for a friend whom is blind in one eye and has limited vision in his good eye.. He regularly competes in matches at out local range.. These are timed matches for AR base rifles targeting steel plates ranging from 100 meters to 500 meters.. Because of his limited vision ability he needed a scope with a powerful magnification in order to see clearly the location of hits/misses on the plates... He had tried a few of the others including my Night Force ATACR w 25 power but just couldn't see well enough from the 300m 400m and 500m plates..
He had been shopping for higher power scopes for a few weeks; the Vortex Golden Eagle was one of his choices so when it went on sale combined with the discount offer I just purchased it for him...
Unfortunately for me his scores at the matches have greatly improved because of this scope and he is now very capable of out shooting me....
