So, I've narrowed down my next scope to a Nightforce. I know I want the MLR2 reticle with mil turrets w/ high speed and zero stop. Only question now is what model. I'm looking at the 3.5-15X50, the 5.5-22X50, and the 3.5-15 F1. I want to use this scope on both my 18" Centurion Arms SPR upper as well as my .308 Rem 700. What do you guys think would be the best choice for me? Is the FFP really that much more useful? I shoot between 100-600 yards. Possibly out to 1000 within the next year or two once I move. Would the extra magnification be useful? I have a 4-14X scope now and at 600 I'm already wanting a bit more magnification. However, I think the FFP would be a useful feature to have when shooting at dynamic distances. As always your thoughts are appreciated. Thanks!
