    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
    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.

    For more information on selecting the correct sights, read our article on sight selection.

      Awsome stuff

      Everything is going good with the new sights but wish they stayed where I put the dot no memory

      We are glad to hear that you are happy with your setup of AT3 products.
      Great value and quality!

      The sights are 1/3 the cost and just as nice as the expensive ones! The flashlight is really low profile and has a pressure switch and it puts out 200 lumins, again awesome value on this one!!

      Thank you for your compliments about the sights you purchased
      Great Value

      The best bang-for-the-buck I've seen that do an excellent job. No complaints.

      Great sight- great value

      These sights are the best sights I've found for the money! Excellent quality and reliability. I (my fault) broke the front sight pin, and AT3 sent me a new front sight for free. Excellent customer service!
