New Rail-mounted, fixed, same-plane front sight works with any AR-style flip-up rear sight as a back-up for a scope or red dot. Distinctive HK-style “globe”-shaped ears aid in fast target acquisition, while the serrated, angled ramp eliminates glare. Elevation adjustable in ½ MOA increments; positive-locking detent ensures settings change only when you want them to. Base with sturdy side clamp and steel crossbolt attaches to any Picatinny railed forend or gas block that is the same height as the receiver rail. Installs with a standard flathead screwdriver—no protruding knobs or levers to catch on brush, clothing, or other equipment. $55 shipped. Email if interested or if you have any questions. Thanks.
