Folding AR-15 Iron Sights: A Plain Overview

AR-15 owners who mount a red dot often add folding iron sights as a backup. A folding set has a front sight and a rear sight that clamp to the Picatinny rail. Folded, they stay low and out of the optic's view; flipped up, they give a normal iron sight picture. That is the idea behind the Ozark Armament FBUIS-B, a front and rear flip-up backup iron sight set for Picatinny rails that folds down for optics. Before buying any folding AR15 iron sights, check how much rail you have in front of and behind the optic, and plan a range trip to zero them. You can read the full listing and buyer reviews on Amazon. A clear plan saves money: decide the optic first, then fit the irons around it.
