Knight's Armament M4 Front Sight

The Knight’s Armament M4 Folding Front Sight is a compact backup iron sight designed for mounting on the top Picatinny rail of a rifle handguard. Originally developed for use within the U.S. military’s SOPMOD program, this front sight features a folding design that allows it to remain low profile when not in use, making it suitable for rifles equipped with optics.

When folded, the sight base extends around both sides of the front sight post to help reduce exposure to impact or abrasion. Available in Black or Taupe, the KAC M4 Folding Front Sight is intended for users seeking a durable, rail-mounted front sight option compatible with standard M4-style rifle setups.
