Holosun HS503CU solar micro red dot multi reticle 2/65 MOA
The Holosun HS503CU is a micro red dot with a 65 MOA circle dot reticle, switchable to the 2 MOA dot only. High-efficiency LEDs and the solar panel allow the optic to work without a battery in many light conditions; the backup battery lasts up to 5 years with the dot only and up to 2 years with the circle dot.
The "U" denotes the housing that protects the windage and elevation turrets on two sides. The optic mounts on a Picatinny 1913 rail and is supplied with low and lower 1/3 co-witness mounts.
