So, I am running a NXS 2.5-10x42 on my 6.5 Saum light weight rifle at present. Great scope, but moving it to my AR15 6.5 Grendel. So, I need to get another scope for the light weight 6.5 rig, and would light to up the top end magnification to 15-18 power. Want to keep the weight as light as possible, 20oz, 25 oz at the most, repeatable MOA turret, and some type of reticle that has hash marks at least on the horizontal plane in order to hold windage. SFP scope. I am used to Nightforce bullet proof quality. Recommendations requested.
