Originally designed for the US military's SOPMOD rifle enhancement program, the KAC M4 Folding Front Sight is a low profile backup sighting solution that is designed to be attached to the top rail of a rifle's handguard. When stowed in the folded position, the M4's sight base extends back to envelope the front sight leaf on the right and left side, helping to protect it from damage.
