Rear-sight aperture has blemish – printed line is crooked. Does not affect function of rear sight.

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

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.

    Tactical front & rear sight set -- Blemished

    The sights arrived quickly and were well protected from damage. These sights are listed as blemished, but the only thing off is the rear sight line which is slightly off center. Once adjusted this will make no difference, and can hardly be seen. I Would definitely buy again for my next AR build.

    Great item!

    These sights were listed as blemished, but came in what I would call "nearly perfect condition". I could not find a single issue with these sights. This item was a great deal, and I cannot wait to do more business with AT3!

    AT3 sights

    The sights look great and function beautifully. Shipping was prompt and packaging was good. Would definitely buy again!

    Great Value - BLEMISHED - AT3 Tactical Pro Series Flip- (BUIS) - Front & Rear Set - Same Plane

    I received this BUIS via USPS superfast. Say's blemished, but I don't see anything wrong. Great quality and works flawlessly. Easy to install and use. Recommend this set to everyone interested in a quality product for BUIS or even as primary front and rear sites.

    Good product good price

    Good functional buis. Blemish insignificant, thanks AT3!
