Nightforce is an awesome piece, if you "drive" a scope a lot like I do (run the turrets all the time for almost every shot) then nightforce, US Optics, and Leupold (usually in that order) is the way to go, Schmit & Bender is a great scope too. There's a ton of good glass out there, but the turrets are another story. I"m curious about the Huskemaw
(sp) scopes, I've never had my hands on one or even seen it in person.
The sighttron I do have experience with, the only two I've dealt with failed, one blew up (nitrogen seal failed and fogged over inside) and the other the reticule rotated after 9 shots out of the box. Glass seemed to be pretty good. I know a lot of people that use Vortex and they seem pretty decent to me, I've shot a few but haven't "driven" them very much.
With all that said, I'm putting a Leupold Mk 4 LRT TMR on my STW, they have one of the best warranties I've ever seen, they stand behind everything, even user abuse (guilty) and they stand up to a lot. I've used them downrange and literally put my life on them like our S&B's and they came out on top. Another plus is I really like the TMR, very easy to precisely Mil a target quickly and the gap in the middle of the cross hair allows for visual on very small targets at long range that could hide behind a crosshair (i.e. prairie dog at 800+) .
So in the end, IMHO I think Leupold is the best bang for the buck in a long range scope
, they are not cheap either, but usually can be had for a bit less than a NF and a lot less than an US Optic or S&B.
