Fast, Accurate Backup Sighting; Push-Button Activated

Machined aluminum, flip-up sights clamp to flattop Picatinny rails for emergency backup sighting if your primary optic fails. Or use alone as reliable “iron” sights that fold down to avoid damage during storage. Lock securely into upright position, while a push-button release prevents accidental lowering if you bump the sight. Can be co-witnessed with non-magnifying red dot and holographic sights. Easily mounts to any MIL-STD 1913 Picatinny rail via a locking bar and slotted, knurled thumbscrew. Dual Aperture Rear Sight offers an exceptionally low profile when folded and features standard military, A2-style double peep aperture; windage adjustment knob provides .48 MOA adjustment per click on M16A3 rifle and .65 MOA per click on M4 carbine. Ranging Rear Sight has a rotating disc with five numbered apertures set for ranges out to 600 yards: “0” for ranges 25 to 200 yards, “3” for 300 yards, “4” for 400 yards, “5” 500yards, “6” 600 yards. Position number is visible to the shooter through a window under the aperture. Windage adjustable for .55 MOA change per click on 20" barreled rifles and .65 MOA change on 16" barreled carbines.
