Drop-in replacement for the mil-spec A1/A2 flip-up rear sight aperture co-witnesses with red dot optical sights and gives you a choice between traditional peep and easy-to-acquire notch. Notch won’t interfere with view of the primary sight’s reticle, so both sight pictures are easy to see, and you can switch between them quickly. Also maximizes field of view during CQB operations, especially in low-light conditions. For more precise targeting, flip up the peep side for a “medium”-sized peep that falls between the two hole sizes on standard A1/A2 sights. Elevation does not change when switching from notch to peep. Precision CNC-machined from 6061 aluminum and hardcoat anodized.
SPECS: Machined aluminum, hardcoat anodized, matte black. .045” (1.16mm) wide notch. .100” (2.6mm) diameter peep aperture.
