The older I get, the harder it is to see without some magnification. LPVO's are my go-to everytime. I have several NF 1-8, & Leupold 1-6 scopes that do great. I don't have any Primary Arms lpvo's, but I have several friends who do and I've been impressed with the PA glass clarity.
You can't really go wrong with a Gen 3 PVS-14. Anything above a 30SNR, EBI less than 1.5, 64lp/mm or higher, HALO less than 1.0, LG above 60k will equal a great set up.
