Very good !! 223rem no problem
The etched reticle is awesome and for $80 would make this a 5 star scope. However, there are virtually no turret adjustments. To adjust windage and elevation you have to loosen a screw, and then the turrets simply unscrew like a bottle cap until it falls off and the barrel of the scope is open to the atmosphere. I guess you are supposed to re-tighten the screw where you want it, holding the reticle in place. I've never seen such cheap adjusters. Also it appears this is not nitrogen filled or fog proof. I've had $10 Simmons scope with better adjustments. So I'm sending mine back, it's just no good. When you get real adjustable turrets, let me know and I'll buy another one.
