Aim-O 551 Red Dot Sight - Black

The 551 Red Dot Sight is the optimal choice when fast target acquisition without magnification is required and there is little mounting space available.

On the 30 x 20mm wide lens either a red or green illuminated reticle is projected. Of course windage and elevation can be fully adjusted. The installation is quick and easy thanks to the large side screw, the brightness can be adjusted on the back in 20 levels, depending on the ambient light. Incidentally, the 551 will switch off automatically after approx. two hours of continuous operation so that the batteries are spared and the runtime increased.
