This backup plan is always in sight.


The Mepro FUBS is a tritium-enhanced set of sights – two tritium vials are firmly inserted in the rear sight, and one tritium vial is inserted in the front sight. In addition, the self-illuminated backup sights are designed to provide the shooter with secondary sights if the primary optics go down.


The advanced Mepro FUBS sights are low-profile, made of strong composite material, and are highly durable. Quickly and easily flip them into position when needed. Sight pin elevation is easily adjusted without tools. 


Day or night, the tritium makes the Mepro FUBS a viable option.


The MEPRO FUBS flip-up’s are advanced, low-profile self-illuminated front and 2-Dot rear backup tritium sights -designed to provide a secondary sighting solution in case the primary optics go down. You can also use it as primary sight. The Mepro FUBS sights are mounted to any Picatinny rail using a 2.5mm Hex key (provided).


GETTING ON TARGET: The MEPRO FUBS offer the most reliable illumination for day or night. Premium grade tritium vials make your FUBS visible in low light and nighttime conditions. Both rear and front tritium sources appear green in lowlight and nighttime. The nighttime illumination is designed bright enough to see them but not too bright to impact the sight picture. Always producing light and always ready 24/7 for 12 Years.


HIGH DURABILITY: The fiberglass reinforced polymer and metal construction of the sights houses the high-grade tritium vial which provides illumination, allowing you to engage targets day or night confidently. A spring-based locking mechanism allows you to flip them into place when needed quickly.


EASY TO ADJUST: The detent knob on the rear easily adjusts windage, and the front sight includes an Indexed, easy-to-adjust Elevation Drum. No tools are required for zeroing.
