An AR-15 rear sight is an aiming device mounted at the rear of the rifle, providing windage adjustment and precise alignment with the front sight for accurate shooting. It can be fixed or flip up and works with AR-15 upper receivers, Picatinny or Weaver rail systems, hand guards, and standard front sights. The rear sight’s essential for backup or primary aiming, making it ideal for tactical, hunting, or competition AR-15 builds, and is compatible with all standard AR-15 components.
