For $45 you won't lose much if you try it but I doubt it will work well. Get a scope with the turrest and your looking at at least $250-$300 for a recent one. If it's going on something like a 223 rem, it'll probably work. For $45, I doubt it can handle much recoil. What are you thinking of putting it on?

I'd suggest to look at Leupolds or Nikons around $300, scope rings for around $40-50 and same price point for bases and mounts. Benefits of paying more for a rifle scope is that it is water and shock resistant and most importantly will hold its zero. Meaning that if you adjust click values, when you decide to return it back to zero, the reticle will be in the same place as before you adjusted. In addition, light transmission plays a big role.
