The A1.5 is a hybrid rear sight that incorporates the A2 Flip-Type Sighting Aperture (large and small aperture sizes) with an A1-Type Windage Wheel that requires a bullet tip or similar tool for adjustment, thereby ensuring that sighting corrections made at the range are not inadvertently altered by rough handling or use in the field.
