Ok so I hate being that guy but Iíve come to the conclusion that itís better to have one top tier LPVO (1-6 or 1-8) and one top tier long range precision optic than it is to have glass on every gun you own. With modern mounting solutions that almost perfectly return to zero and turrets that truly track it is very possible to do as well. Just record what it took to rezero when you move the optic and when you move that scope back to the original input the offset and confirm zero.
I have managed to get some decent glass over the last few years and review some. LPVOs being vortex razor, night force NX8, Trijicon accupower, EOTech vudu, Burris XTR II, leupold MK6, Steiner and a few others below that grade of optic for long range Iíve got or been behind razor genII 4.5-7, leupold MK5 both models, Burris XTR II, sig tango 6, viper gen II, and a few others
You absolutely pick up capability with the top tier optics. Optical clarity in all lighting and target area is incredibly better with the best optics, the turrets tracking and having a SF knob for parallax is crucial, your reticle selection is also better and will measure true.
Iím considering a Nikon FX1000 for a .17HMR but the turrets suck for dialing as the individual detents to stop on are to close and itís difficult to stump where you need them. The king and queen of the sub $1000 price range will be the XTRII and the Viper Gen II. While not perfect these have show they are 1k yard optics that can be had for below a grand. They might not be the clearest glass but mechanically they have what it takes. If you are serious about trying to shoot long range precision past 500yds on game animals besides targets then you need to seriously be considering going to something that will have better clarity and light transmission suck as the MK5, razor gen II, or NF NX series of glass. Remember eye strain is not a good thing and the lower end options will give it out faster than the nice ones. Iím personally a fan of mill biased Christmas tree reticles in anything thatís going to do true long range work. Illumination is nice but unless your doing low light you wonít need it so why pay for it. first focal plane is a non negotiable feature on anything over 6x for me. I know guys running the primary arms optics and while they work I wouldnt drop below the gold line. Glass really is buy once cry once. So itís worth waiting a year if it takes it to buy the upper class of glass.
