Re: S&B model question
Turrets are the difference. Both are H2CMR reticle with CCW elevation turrets (rotate the turret counterclockwise to dial in elevation.)
The top one you listed is missing a turret style. You can get S&B's with different style elevation turrets; the abbreviations are MT (multi turn), DT (double turn), MTC (more tactile clicks), or MTC LT (more tactical clicks, locking turret.)
I'm not sure the MT elevation turret is available on the 5-25 but it is available on other models such as the 12-50.
The MTC knobs have the standard clicks every 0.1 mil but a heavier detent/click every full mil.
