ATI Flip Up Polymer Front & Rear - Back Up Sight Set

The ATI Tactical Flip-Up Sight Set is a same-plane polymer backup iron sight solution for AR-platform pistols and carbines — a matched front and rear set that provides a reliable aiming option when a primary optic fails or is removed, at a price point that makes adding BUIS to every build practical.

The front sight features an adjustable A2 post with a spring-loaded posi-lock design that automatically locks into position when raised, maintaining zero every time. The rear sight offers windage adjustment and two apertures for switching between close-quarters and longer-distance targeting. Same-plane geometry aligns the sights level across both receivers and Picatinny rails for a uniform sight picture without shimming or modification. Both sights fold flat when not in use, keeping the rail clear for optics while maintaining instant accessibility. Attaches to any standard Picatinny rail section without tools.

Material: polymer. Configuration: same-plane front and rear set. Front sight: adjustable A2 post, spring-loaded posi-lock. Rear sight: windage-adjustable, dual aperture. Rail interface: Picatinny. Color: black.
