I recently ordered a KAC SR25 EC 16" gun that i would like to use as a semi auto precision setup.I probably wont receive the gun for at least a month so i would like to have a scope ready when it comes.First off I am a noob in the precision world and I want to make sure i get the right scope for my needs. I plan on shooting out 500yds mostly but would like the ability to stretch it out further as i get more experience. The two scopes i have been looking at are the Mark 4 LRT Leupold 3.5-10x40 and the Nightforce 2.5-10x32. I must admit I really dont know much about the different reticle styles and which one will best suit my needs. I understand the SR25 is not going to give me bolt gun accuracy but i want to maximize the potential of the platform but staying in $1600 price range for glass. Any suggestions or input is greatly appriciated!
