Overview
A Sightron S-TAC 1-4.5x24 SR1 service rifle scope built for CMP and NRA High Power competition, with an ExacTrack windage and elevation system, MC-333 multi-coated lenses, and a matte black aircraft aluminum tube.
The SR1 reticle pairs an MOA circle with a center aiming dot and horizontal and lower-vertical stadia lines meant to draw the eye to center quickly, a design aimed squarely at service rifle competition use rather than general hunting. ExacTrack keeps the erector tube in constant contact for consistent adjustments, which one owner review confirms in practice, though another reports the elevation mechanism working loose after months of use.

Who it's for
