Our simple and rugged 300 Meter Folding Rear Sight is more economical than the adjustable 200-600 Meter Rear Sight, and features a fixed post aperture that is ideal for shooters who want an easy to use, close to medium range back-up sighting solution. The 300 Meter Rear Sight is adjustable for windage only, and includes a snap-in polymer aperture insert that gives the user a more precise sight picture if desired.
