UTG AR15 Low Profile Flip-up Rear Sight with Dual Aiming Aperture

The UTG AR15 Low Profile Flip-up Rear Sight with Dual Aiming Aperture is a proven backup aiming solution for modern tactical carbines and competition rifles. Designed for shooters who demand a compact, reliable rear sight that doesn't interfere with optic mounting systems, this sight serves as essential insurance when primary optics fail or require battery changes. Law enforcement, military personnel, and civilian shooters operating in demanding environments rely on dual-aperture rear sights to maintain accurate shot placement across varied engagement distances without adding unnecessary height to the receiver.

The dual aiming aperture design provides both a primary aperture for close-quarters engagements and a secondary, smaller aperture optimized for precision shooting at extended range. This engineering approach eliminates the need to switch between different sights while maintaining the low-profile footprint critical for AR15 platform integration. The flip-up mechanism allows instant deployment when needed and folds flat against the receiver when not in use, preserving rail real estate for forward-mounted optics or other accessories. Weighing only 0.15 lbs and measuring compact dimensions of 2.85 x 1.4 x 4.2 inches, the sight adds minimal profile or weight penalty while delivering battle-proven functionality that has been tested by armed professionals.

This rear sight is optimized for AR15/M16 platform rifles and integrates seamlessly with Picatinny rail systems found on most modern tactical carbines. Installation requires no gunsmithing—simple clamp-down mounting to a standard receiver rail ensures secure positioning without permanent modification. The sight performs exceptionally well in backup roles, competitive shooting scenarios, and as a primary aiming system for shooters preferring iron sights over optics. Whether you're outfitting a duty rifle, precision build, or maintaining a redundant aiming capability on an optic-equipped carbine, the UTG AR15 Low Profile Flip-up Rear Sight delivers dependable performance at a practical price point.
