Knight's Armament M4 Front Sight (99051)
PN:99051
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.
