    Sleek and lightweight, durable and accurate - the AT3 Pro Series Backup Iron Sights are the ultimate value in AR-15 iron sights!

    Accurate and Easy to Use

    • Standard A2 sight design makes these easy to sight in. Adjustable front sight post controls the elevation, and the rear sight features a simple knob for windage adjustment
    • Rear sight features a dual aperture - a large aperture for rapid target acquisition in close-quarters, and a small aperture for long-range precision shots.
    • Low-profile - sights fold down to only 7/16" height when not in use

    Durable Design

    • Lightweight, durable 6061 aircraft aluminum body, with mil-spec hard-coat anodized finish.
    • Steel mounting bolts provide un-moving accuracy. Recoil-tested hinge and secure locking mechanism
    • Backed by the AT3 Lifetime Warranty

    Simple Installation

    • Mount on any standard picatinny rail such as a flat-top upper and quad rail handguard
    • "Same Plane" sights - the front and rear sights must be mounted at the same height. These will not work with gas blocks that are lower than the height of the upper receiver
    • Add the optional front sight tool to make it a breeze to zero your sights! Save $3.95 when you add a Front Sight Adjustment Tool for only $8.

    Please Note - Since these are "same plane" sights, the front and rear sights must be mounted at the same height on the rifle. If you are mounting on a gas block that is lower than the upper receiver, check out our gas-block-height sights.

      Good product for the price

      Sights came fast, although I haven't had time to shoot with them yet ,they appear to be well made and went on easy with no problems. Good price and good product.

      Like them.

      Nice set for the money. Would recommend.


      Go on fast shoot great right after they are put on.

      Thank you for the feedback Richard!
      Just what I needed

      Not bad. Besides these are backup sights.

      Thank you for the feedback Bruce!
      Not too bad

      Sights are sturdy and accurate. The only issue with the set I received was the springs are weak when flipped up. You barely touch them and they move and don't spring back. Kind of a bummer.

      We are sorry to hear about this issue and would be happy to replace these sights with another set if you wish.
