Aim-O Target Optics 551 Red Dot black

The 551 holographic red dot visor is based off of the world-famous EO-Tech version. Just like its role model, the reticle has an inner point with an outer circle. It can be mounted on all common 22 mm Picatinny rails using a screw. The reticle is adjusted using two adjusting screws on the right-hand side.
