Flip-up rear sights fold flat against the top rail when not in use, maintaining a low profile that does not obstruct the field of view through a magnified optic or red dot. When needed, the sight deploys upward with a button press or thumb push and locks into the vertical position for iron sight use. Most flip-up rear sights are designed to co-witness with a compatible front sight at the appropriate height — lower-third co-witness sights appear in the lower portion of a red dot window, while absolute co-witness sights appear centered in the optic window. UTG flip-up rear sights mount to standard Picatinny (MIL-STD-1913) rails and are compatible with standard AR-15 flat-top upper receivers. Windage adjustment allows the rear aperture to be shifted left or right to zero the iron sight system for point-of-impact correction at the intended zero distance.

Frequently Asked Questions

What does “45 degree” mean on this rear sight?

A 45-degree offset rear sight mounts at a 45-degree angle to the side of the top rail rather than upright on the rail surface. This allows a magnified optic to remain mounted and zeroed on the top rail while the 45-degree iron sights serve as a close-range backup — the shooter rolls the rifle 45 degrees to bring the iron sights into alignment for fast close-range engagement without removing the optic.

What is ACCU SYNC on UTG sights?

ACCU SYNC is UTG’s adjustment system for windage and elevation on their flip-up and offset sights. It typically uses a tool-assisted or coin-slot adjustment mechanism with audible click detents for precise, repeatable sight adjustments during zeroing.

What rail systems is this compatible with?

This 45-degree flip-up rear sight mounts to standard Picatinny rails on AR-15 flat-top upper receivers, positioned on the side rail section at a 45-degree offset from horizontal. Confirm your upper receiver has a rail section at the appropriate offset position before ordering.
