I would not even wast the money on a Barska. You would be better served by going with a Bushnell Trophy
or Simmons Master Series Aetec
Another one to think about is a new comer to the optics world Muller Optics
. Good quality for the price. I know a few Varmint hunters that swear by Muller.
A lot of your price depends on how much power you are wanting for your rifle. I think 2.5-10 power should work at most 3-12 power. But that is up to you.
I have right now
Rem 700 VLS: Leupold VX-II 4-16x40mm
Rem 1917 Enfield 308: Bushnell Elite 4200 6-24x40mm
Rem Mod 30Express: Simmons Pro Hunter 4-16x40mm
Rem 511-x (22lr): BSA 4-16x40mm It works good for a rimfire but I would not trust it on a centerfire.
I also have a BSA Platinum 36x42mm target scope (Does not hold zero) and a Weaver KT-15. That weaver if you can find it used for around $200 is a great scope. it is a stright 15 power. Has a good field of view great clarity and good light transmission. It might replace the Simmons on the model 30. Not sure yet though.
