For Fast Target Acquisition & Improved Accuracy
Barrel-mounted, dovetail Bullseye sight gets you on target fast with perfect alignment for improved accuracy. Steel, double-ring peep design ensures consistent sight alignment and helps improve shooting form. The moment the rear sight is misaligned, the front sight drifts out of the center ring, telling the shooter to re-align. Replaces standard 3⁄8" dovetail rear sights on many rifles. For use with bead-type or traditional blade front sights. Adjustable models are available with a short or long base and six-position step elevator that’s adjustable in .030" increments for precise elevation settings. Fixed model features the same Bullseye peep design but without the extended base and is not elevation adjustable. All models are drift adjustable for windage. May require minor fitting.
