I want to stay under the $2,000 production class rules for a scope but want all the bells and whistles. I have several NF models and a Razor HD. I have stared at Athlon BTR 4.5-29×56 APLR5, Bushnell XRS II Elite Tac 4.5-30x50, or Burris XTR III 5.5-30×56mm. Not to add to the pile which one would be the best choice?
