Best scope for any ar / ak platform, and many high caliber riflles - Leapers AccuShot 3-12x44mm Illumination Enhancing Mil-Dot Rifle Scope

Clear glass, no internal reflection from illuminated reticle. Easy and sturdy locking turrets for windage and elevation to get and stay on target, zero'd in.

Love the included medium height rings, though some may want high profile rings depending on the rifle. The diamond locking nuts on the rings clamp to the picatinny is better than the UTG lever style. These are rock-solid, I have broke the lever type, but not the hand-tightening thumbscrew or diamond head type like these. Excellent.

Also, at 3x its good to go for moderate CQB to MQB (close to medium range) as it can act as a red dot with a 3x magnifier with a good eye box and fast focus eye bell.
