Daniel Defense A1.5 Fixed Rear Sight — AR-15 Black

Description

The Daniel Defense A1.5 Fixed Rear Sight is a lightweight, low-profile backup iron sight engineered for use with modern reflex optics on AR-15 style flattop uppers. Its one-piece, streamlined form does not impede charging-handle operation on M4-type rifles and installs directly to a Mil-Spec flattop upper receiver. The sight is secured using a slotted fastener threaded into a self-locking steel insert and uses Rock and Lock attachment technology. It is set at absolute cowitness height and offers dual apertures suited to a range of sighting preferences.
