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. Gas Block Front Sight clamps to a gas block with a Picatinny rail on top; A2-style front post is adjustable for elevation with ¼ turns for 1.25" MOA at 100 yards. Protective “ears” guard the post; deep grooves on the outside of the ears provide extra purchase for quick deployment.
