Spike's Tactical Rear Folding Sight – AR-15/M16 Picatinny Mount

The Spike's Tactical Rear Folding Sight is a spring-loaded backup iron sight designed for AR-15 and M16 platform rifles. This sight deploys with a positive click and locks securely in the upright position, providing reliable aiming capability when optics fail or as a co-witness option with red dots and holographic sights. The low-profile design folds flat when not in use, protecting the sight during transport and storage.

Constructed from hardened steel with a matte black finish, this rear sight mounts to any Picatinny rail system and requires no tools for installation. The dual-aperture design offers both a large peep for close-quarters engagement and a smaller precision aperture for longer-range accuracy. Windage adjustments are tool-free and provide audible clicks for repeatable zero retention.
