Product description
These units have slight cosmetic blemishes – no defects in mechanical function.
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.
