Daniel Defense Rock & Lock Fixed Iron Sight Set (Front & A1.5 Rear)
Daniel Defense Rock & Lock fixed iron sight set consisting of the A1.5 Fixed Rear Sight and Rail-Mounted Fixed Front Sight. Lightweight, streamlined fixed sights built for use alongside modern reflex optics without impeding charging-handle access on M4-type rifles.
Both sights use Daniel Defense’s patented Rock & Lock attachment technology with a one-piece design and slotted fastener. The front sight mounts to any MIL-STD-1913 rail and features a contoured profile that supports forward placement of compact weapon lights.
