Ultradyne USA C4 Folding Front/Rear Sight Combo – AR-15 Backup Iron Sights

The Ultradyne C4 Folding Front/Rear Combo provides reliable backup sighting when optics fail. These low-profile folding iron sights deploy quickly and lock securely in the upright position, offering shooters a dependable secondary sighting solution for AR-15 platform rifles. The C4's compact folding design allows co-witnessing with red dots and magnified optics while staying out of the way when not needed.

Machined from steel with a corrosion-resistant finish, both front and rear sights mount to standard Picatinny rails via low-profile bases. The rear sight features windage adjustment for zeroing, while the front post is elevation-adjustable. Spring-loaded detents hold sights firmly in both folded and deployed positions. The sight picture delivers a clear, uncluttered view for rapid target acquisition at close to intermediate ranges.
