The Fab Defense FX-RBS is an innovative, unobtrusive, and resilient auxiliary rear sight. It's compatible with all front sights and is engineered for maximum optical efficiency. It's easily attachable to any 1913 Picatinny rail, perfect for M4 / AR-15 / M-16 platforms. Whether you use it as a primary or back-up sight, the unique angel-wing-shaped front shroud aids in image centering with any front sight.
Its sleek, low folded profile is designed to prevent snagging on gear, webbing, or natural obstacles. The dual apertures of 3mm and 1.5mm cater to different needs - the 3mm aperture can be used for long eye relief mounting, low light conditions, and quicker target acquisition, while the 1.5mm is perfect for close eye relief mounting and improved accuracy.
Constructed from high-quality polymer and metal, the sight is extremely sturdy. It features a quick spring-locked deployment mechanism that promises durability and won't slip, break, or deform. This model comes in a stylish black finish.
