I am looking to build a dmr/ mid range shooter using my poly m308 aka m14 clone. I had a few questions regarding my scope choice. After doing some research I am leaning towards the nikon monarch M5 4-16x42 or the M tactical 308 4-16x42. With that said one of my questions is other than the turrents and retical what is the difference between the two? Question 2, is the monarch worth the extra $200 when compared to a similar prostaff. Last question and iknow this question is very subjective, but based on your experience is there a better option in the sub 500 range? Thanks guys and gals
