Low-profile EXD Backup Sights from Mission First Tactical are crafted from steel for ruggedness and nitride coated for corrosion resistance. They tuck perfectly under illuminated aiming devices while maintaining a strong secure backup solution in the event optics and other accessories fail. The front sight post is adjustable for elevation and threaded for AK pattern posts. The rear peep sight, with adjustable windage via its low-profile knob, provides rapid and accurate target acquisition. Both sights feature low-profile bases and a slim profile and are 1913 Picatinny rail mounted. Retail: $99.99/Front sight; $124.99/Rear sight. Contact: www.missionfirsttsctical.com
