The Mepro FUBS are tritium-enhanced, self-illuminated front and rear back-up sights designed to provide the shooter secondary sights in case the primary optics go down.

The advanced Mepro FUBS sights are low-profile and extremely durable. Quickly and simply flip them into position when needed. Mepro FUBS sights mount to any Picatinny rail. Sight pin elevation is easily adjusted without tools. 

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