Spike's Rear Folding Sight

The Spike's Rear Folding Sight is a low-profile backup iron sight designed for tactical rifle systems and AR-pattern platforms. This rear folding sight serves as a secondary aiming system when primary optics fail, get damaged, or require co-witnessing with a magnified scope. Folding sights are essential components in professional duty and competition carbine builds, offering rapid deployment without adding permanent height to the receiver.

Rear folding sights function by allowing the aperture assembly to rotate down and lie flat against the receiver when not in use, preserving sight picture clarity when forward-mounted optics are primary. When deployed, the sight presents a standard peep aperture for precision aiming at distance. The folding design eliminates the snag hazard associated with fixed sights and provides a clean receiver profile for accessories and mounting systems. This configuration is particularly valued in patrol and tactical scenarios where space behind the optic is limited and the sight must remain accessible but non-intrusive.

Spike's rear folding sights are purpose-built for AR-15, AR-10, and compatible modern sporting rifles across military, law enforcement, and civilian marksmanship communities. Shooters who rely on folding backup sights typically operate in environments where redundancy is critical—whether in combat-oriented training, duty weapons qualification, or competition carbine events. This sight type is preferred by users who demand quick transition capability without the weight penalty or obstruction of permanent aperture systems.
