2-7x32 or 3-9x40 would be my choice. Not lower end, but doesn't need to break the bank. Something of decent quality... like Leupold, Redfield, Sightron, Nikon, Vortex, etc. You can get a damn good scope that will do everything you need for $200-$300. I personally like the duplex reticles, rather than the BDC types...but that is personal preference. SWFA or Optics Planet have nice prices, often some excellent sales. Get a decent base and ring, not sure what folks prefer for that rifle. I like Warne, Leupold, Weaver.
