There are too many trade offs to cover in selecting a rifle scope. I wanted to purchase a NF scope for my last rifle. It just didn't make sense to attach nearly a 3 lb scope to a light weight rifle IMO. The NX8 runs around 28 ozs but with integrated rails on my long action and eye box challenges, it really created some concerns for me. Swarovski needs to figure out their turrets. X5's have a elevation turret the size of grain silo and all the others seem to have limitations and plastic BT's. Schmidt are great scopes, but are really pushing the $3500+ range to get what I would want. I ended up with a Zeiss V6 3-18x50. Works well for my purposes and bought it new for $1799.
