As others have asked, What is your budget?
Whatever you buy, I’d go with something with a minimum of 20x on the top end. This ensures that when on 14-16x or so your sight picture is still fairly bright and the target easily discernible at a mile or similar distances.
My Schmidt Bender PSR 5-25x56 sight picture starts to darken at around 21x but at 17-18x where I’ve shot at a mile is nice and bright.
Some possible options I would consider: NF ATACR 5-25, 7-35, Vortex Razor 4.5-27 (solid glass, can be had for ~$1500-1700 in the PX), Leupold Mk5 5-25, Schmidt Bender 5-25 (can be had for $2200 or so in the PX). People say good things about Athlon scopes but I’ve never used them. Even an old 16x leupold Mark 4 would work. Has tons of internal adjustment and paired with a 20 MOA base would get you there.
Don’t cheap out on the glass if ELR is going to be your space.
