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. 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).
