Troy Folding Dioptic Rear BattleSights are rugged, reliable and BattleReady. The Folding Rear sight is a rail-mounted alternative to a standard A2 rear sight. Machined from hardened Aircraft Aluminum and finished in Mil-Spec hardcoat anodizing and assembled with stainless steel components. The rear sight must be mounted at the same height plane as the front sight. Railed gas blocks that are lower than receiver height will not zero properly.
