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
- 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
- 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 choosing the best AR 15 iron sight.

After searching for a set of BUIS for my rifle, I found AT3 and was pleased with the personal service and product guarentee. There was a slight issue with my order and the team at AT3 went above and beyond to make it right. The sights are made well, metal not polymer and priced very competitively. I highly recommend this product and AT3, they back what they sell!!
great company great site
I love the sights, they work great together and they work great on my .300AAC Pistol build. They are very sturdy and extremely well made, no plastic pieces that I see or feel which is great for durability and longevity. The only downfall to them is they don’t “pop up” you have to push them up they aren’t spring assisted. But for the price and quality they absolutely cannot be beaten and are worth more than they are selling them for compared to every other BUS set on the market. Thank you so much AT3 I will be ordering again soon!
Good price and order was what i expected
Had tons of hope for these sights since they aren't the cheapest but not the craziest either. Figured I'd found a happy middle ground. Nope. Arrived broken my $29 Amazon sights were a better quality then these ones. They are definitely not a low profile set either. They sit higher then the Magpul ones. Just get the Magpul ones....
