The Fab Defense FX-FBS is a top-tier, unobtrusive, robust auxiliary sight that can be used in conjunction with any rear sight. It is specifically engineered to provide a significant visual edge, with an easily adjustable sight pin elevation that eliminates the need for manual tools. The FX-FBS fits effortlessly on any 1913 Picatinny rail and is particularly suited for use on M4, AR-15, and M-16 platforms.
Its versatility allows it to function as a primary sight or a reliable backup. The unique angel-wing-shaped front shroud aids in centering the image with any rear sight for optimal visual alignment. The sleek, low-profile folding feature is designed for minimal interference, ensuring it won't catch on gear, webbing, or shrubbery.
Constructed from high-grade polymer and metal, the FX-FBS is exceedingly resilient. It boasts a spring-locked deployment system that is instant, secure, and resists slippage or deformation, maintaining its structural integrity at all times. This model comes in a sleek black finish.
