An AR-15 fixed rear sight is a non-folding iron sight mounted at the rear of the rifle, providing a consistent aiming reference for accurate shooting. It is typically adjustable for windage and pairs with a front sight for proper target alignment. The fixed rear sight works with AR-15 upper receivers, Picatinny or Weaver rail systems, handguards, and standard front sights. It’s ideal for traditional, tactical, or backup sight setups, ensuring reliable, always-ready aiming on AR-15 builds.
