This unique set up allows for lightning fast transitions between long & close range targets without the need to mess with your primary optics settings.RAOS are manufactured to the highest quality standards & are quality control checked in the USA. These are NOT cheap Chinese made toys. As part of our durability testing the RAOS were put through a 5,000 round torture test & have been deployed on Competition rifles as well as duty rifles for Military and Law enforcement personnel.ADG's goal was to produce the highest quality rapid transition sights possible and bring them to market for a price that would not break the bank of the shooters who support us.SPECS:- Designed for the AR-15/M4 platform.- 45 degree offset with same height above bore as standard M4/M16A4 sights.- ½ MOA elevation & windage adjustments.- Low profile design will not interfere with primary optic.- Mounts directly to the top picatinny rail of your rifle using a flat head screw.
