An AR-10 flip up front sight is a foldable iron sight for AR-10 rifles in .308 Win or 7.62×51 NATO. You can deploy it quickly or fold it flat when not in use. It serves as a reliable backup aiming option alongside optics. The sight mounts to Picatinny or Weaver rail systems on AR-10 upper receivers and handguards. It pairs with standard AR-10 rear sights for a complete iron sight setup. Choose this sight for tactical, hunting, or competition AR-10 builds.
