Hello all, I'm looking at getting into either a Us optics B25 or er25 or Nightforce Atacr 5-25 f1 for a new build. I already have a Nightforce Atacr 7-35 on another rig and like it well enough. New scope would be used for prs and steel matches and the occasional f class. How do the scopes stack up in regards to tracking, eyebox and glass quality. I've never owned a USO product. Not interested in other brands at the moment. Thanks gents
