Pro Series AR 15 Flip-Up Backup Iron Sights (BUIS) – Front & Rear Set – Same Plane – IS-09

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
• Front sight post can also be replaced with aftermarket A2 compatible front sight posts.

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 $2 when you add a Front Sight Adjustment Tool for only $6.

Please Note – Since these are “same plane” sights, the front, and rear sights must be mounted at the same height on the rifle.
