Spring-Loaded, Dual Range Flip-Up Sight For Use With Or Without Optics
Rugged aluminum and steel flip-up rear sight regulates properly with A2-height front sights and can be co-witnessed through an optic. Dual apertures are calibrated for close- and mid-range targets, simply aim through both or fold the first one down and use the second aperture. Easily mounts to a Picatinny receiver rail; locknut is retained by a safety wire, so you can’t lose it. Non-snagging lever instantly releases the spring-loaded sight into the ready position. #40 Std. A2 is 1" high from top of flattop when folded and has A2 apertures calibrated for 250-300 and 500-600 meters. Windage is click adjustable in increments of ¾ MOA. Compact #40L models stand only 5/8" high from top of flattop when folded. All feature a dual-function notch in the top of the aperture leaves that’s designed for ultra-fast target acquisition at ranges under 50 meters, and also serves as a ranging aperture at 400-600 meters. #40L Low Profile is calibrated for 250 and 300 meter combat ranges, with windage adjustable in ¾ MOA increments per click. NSN #1005-01-575-3508. #40L-SP features “same-plane” apertures, so the operator can switch between large and small apertures without worrying about them being zeroed to different ranges. Windage adjustable in ¾ MOA increments.
