As good as it gets in this price range. - Burris Fullfield II 3-9x40 mm Rifle Scope 1in Tube Second Focal Plane

This scope is clear, very easy to use, and is not too heavy. I put it on a 300BLK AR15, zeroed at 100yards. The reticle trajectory compensation hack marks are in meaningful spots for both my supersonic and subsonic loads. Bushnell’s online tools print an accurate range card for any load and reticle combination.

This is not a scope that is designed to have its turrets twisted on a regular basis. They are steel turrets that have a coin slot to ease turning them; without the coin, they are not easy to adjust-not impossible. This scope is best used with the reticle holdovers for range adjustments. They work well for me. Well enough that I ordered a second one of these scopes.

If you want a scope in the same price range that can be dialed easily, look at the Burris E-1 scopes. I think either model will easily get you out to 600yards with an appropriate caliber-pretty nice for under $250.
