Re: Opinions on Leupold and Nikon quality
My opinion, short of ability to hold zero, glass quality should be your number one concern. That said, Nikon has excellent glass quality for the price point you are looking at. Where they and lupy fall short is in other areas. I can't think of a single ranging reticle that Nikon makes that's worth a darn, unless you think the mil-dot is a good reticle (i don't).even then the turrets are going to be calibrated in MOA and won't match the reticle.I've looked through several of the monarch editions, though - very nice glass but if you want the mildot reticle i believe you are going to be over the $1k mark. The other downside to all but the $1k+ Nikons it seems is the tube diameter is only 1 inch, which limits windage and elevation adjustment.
I just got my first Leupold today (mk4 m5 turrets ffp tmr reticle) and i am very impressed with the glass. It's not in your price point but all mk4 scopes use the same glass. I only went with this one because it is the only one that has a mil-based reticle with mil turrets. I LOVE the TMR reticle, though, and if you can deal with having non matching turrets i believe you can get a mk4 in the 3.5-10x zoom with the TMR reticle for right around the $1k mark.
Like i said, glass quality on both are excellent. I have owned a nightforce and don't think the glass was all that great. Not bad, but i think you're spending the $ on it more for the ruggedness.
Many will steer you toward the vortex viper line. I own one. I bought the lupy to replace it so it's for sale. I LOVE the features the pst offers, but ffp, matching turrets, zero stop, illuminated reticle are all features that mean nothing if the glass is only so so. I thought the lack of clarity was just a fluke with mine until i looked through two more at my local shop and saw the same thing - fuzzy picture. Then i looked through a mark 4(and a low end Swarovski-amazing glass!) And saw what i wanted - a crisp, clear picture!
