What are you looking to improve?
What are you missing from your current rifle scope?
Ive gone from an old Nightforce NXS to a Delta Stryker since the old 5 MIL per rev turrets with no zero stop would be terrible at a competition, otherwise I had no issues with the Nightforce on that rifle.
Ive gone from a Vortex Razor G2 to a Schmidt PM2 which was a very noticeable optical upgrade, but the turrets were just fine on either of them. I could go on, but you get the point.
