The Razor is just hard to beat for an all around optic.
Dead nuts reliable
Great Glass
Great Reticle
Turrets are fantastic and easy to use.
Big Forgiving Eyebox
One of if not the best warranties in the industry.
Best Value there is in the optics game. Competes well with optics costing $1k+ more.
Is it the best optic for everyone? No , everyone has their preferences and if you want to get a better scope you can spend more than 2X as much and do it (TT or ZCO).
But for the vast majority of shooters it does everything you need it to do and its reliable. Its why it has been one of if not the most popular long range scopes for almost a decade now.
If you really are concerned about weight, then the AMG is also one of the best crossover optics out there.
It really depends on what your trying to do. PRS? Field Shooting? Hunting? Stalking? Military/LE? Little bit of both? All those things factor into what will work best for you.
For Strickly PRS , The Razor is really hard to beat. If you could get a Minox ZP5 with MR4 for like $2kish, that would be certain upgrade on glass and reticle, but a downgrade on warranty service and turn around. Otherwise Pony up for a ZCO and be done with it. Those are the 3 optics I would spend money on.
The NX8 really does not compare favorably other than its weight to others in this price range. Much better options out there IMO.
