Aim-O red dot sight SRO Black

"This small electronic device is used to make aiming easier. A bright red dot is reflected by the front glass and moves along with the natural lateral movement of the user, projecting quite accurately the aiming point of the replica. It is made of high-quality aluminum, being lightweight and resistant. It can be mounted on a standard Picatinny rail and secured with an easily accessible large screw. The dot can be adjusted both vertically and laterally. It operates with a CR2032 battery that is mounted between the bottom and top parts. To access the battery, the two screws on the top part need to be removed. The device automatically turns on when the buttons on the sides are pressed. Included in the package is a plastic cover for protection during transport, as well as a screwdriver for adjustment which will be used together with the plastic adjustment disk also included in the package."
