Vortex scopes?

If you don’t want to click turrets, they’re decent. The more expensive you go, the better they are, but the cheaper Chinese built ones are spongy turrets, scratchy focus and parallax rings, and feel a little cheap. That being said, my crossfire 2 is rated for magnum springers (I originally had it on a Diana 460 mag) and the glass is pretty damn good for the price!
 
I have a 4-16 Diamondback. It's all around a good scope for the money. As mentioned the only real gripe is the turrets are a bit spongey for a tactical scope.

My Primary Arms scope has much better turrets at half the price. The only thing that stopped me from buying another one was the Mrad reticle MOA turret combo.

I have several Primary Arms scopes and will probably get more.
