Cheap irons often don't track...
That said cheap irons can be used like Leupolds. Set and forget. Shoot for group not accuracy.
I don't need anything too fancy, just something to beat the other guys at my club with... A couple of them have some pretty damn fine H Bar's, but their antiquated military sights are just that. We will see how well these "cheap" sights do after I get them.. I'm going to be putting them on my Noveske, and it is probably my least accurate ar, besides my Armalite AR10T 308w. These ar's are still a learning experience for me and it will be interesting to see how these new sights do. I'll post up results, but don't worry rost, I'm likely not going to touch your score, unless you piss me off.
