Description
Holosun 503CU Micro Red Dot Sight, 2MOA Dot Only or 2MOA Dot with 65MOA Circle,
Fits 1913 Picatinny Rail, Black Finish
Red Dot Sights have their origin from aircraft gunsights or 'collimators' where the shooter's reticle is projected on a clear lens/glass pane allowing for easier target acquisition and a clearer sight picture of a target, later adapted for smalls arms rifles, red dots exist to be incredibly sturdy, and reliable open sight picture 'optics'. Red Dot Sights(RDS) allow for faster target acquisition due to their wide-open glass nature and featuring almost unlimited eye relief as the projected reticle is reflected off of the glass and back into the shooter's eye. meaning you can see your point of aim from almost anywhere on a rifle or pistol. The AR-15 platform was adapted for use with these aiming systems back in the late 80s where the carry handle was being sidelined in favor of the distinct Flat-Top / Picatinny rail system.
About this Sight System:
The HS503CU is a new micro red dot optic equipped with a 65 MOA circle dot reticle with the option of switching to a 2MOA dot only. Holosun's highly efficient light emitting diodes and solar panels allow Holosun solar optics to run without a battery in many lighting conditions. Additionally, the back-up battery lasts up to 5-years on the dot and up to 2 years on the circle dot. The "U" signifies a housing design that shrouds the windage and elevation turrets on two sides.
