The Mission First Tactical Back-Up Polymer Flip-Up Rear Sight helps get that perfect shot every time. Unlike other back-up sights, it features a shroud that shelters the aperture from debris and impact damage when not deployed, and the whole sight folds safely to the rear if dropped. The slim, low profile allows the sight to sit under all current magnifiers and optics, giving it a snag-resistant design.
A dual-peep, same-plane aperture allows for perfect co-witness, meaning a friend or partner sees exactly what you see. Works in conjunction with all standard-height front sights. Mounts onto a 1913 Picatinny rail. A flat head screwdriver is required to adjust an Infinite MOA. Manufactured using a specially-developed, Military Grade reinforced, super tough polyamide. Windage adjustment. Made in the USA. Dimensions: 2.23" x 1.08" x 0.88".
