From your list I'd pick the Nikon m308 but I'd suggest going with the Sightron S-Tac 3-16 as Uisge suggested, I have one on my Modern Hunter and it's a great little scope for around $1000. I order my Sightron scopes through Jerry at Mystic Precision, great guy to deal with.
Thanks for the referal... The STAC3-16s are $700
Another great options in the FFP Xmas tree scope with excellent glass and 6-24 mag, Athlon Argos BTR. Similar quality of glass and costs to the STAC.. I was really surprised and have checked it a number of times out to 800yds on a chimney and the resolution is fantastic.
For a higher mag variable with solid tracking, reticle features, FFP and optics all at a great price, the Argos BTR is my #1 pick
The Athlon Talos BTR is a great entry point especially for mid and closer range viewing. All the bells and whistles in a FFP variable... less money but a step down in optics.
For those with a higher budget, the Midas lineup has several new offerings in both SFP and FFP... more geared to LR hunting and varminting.
Then you go higher to the Ares BTR which is what I am currently running on my rimfire and centerfire PRS rigs.
Cronus BTR tops the list and has some awesome glass and features. I look forward to the upcoming Ares ETR which is supposed to bridge the gap between the Ares BTR and Cronus and priced right in the middle too.
Very happy with the Athlon products to round out my FFP offerings.
