Design Philosophy

Back-up iron sights remain an essential component of any serious rifle setup. Whether you're running a red dot, scope, or other primary optic, these folding sights ensure you maintain a fighting capability if your main system fails. The tritium front post eliminates the need for ambient light to acquire your target, making this system effective in any lighting condition.

Practical Application

Ideal for defensive rifles, competition platforms, or any AR-15 where reliability and redundancy matter. The folding mechanism keeps the sights out of the way during normal operation while remaining instantly available when needed.
