This backup plan is always in sight.
Out of your way, but never out of sight.
The Mepro FRBS/FUBS/FABS tritium sights are flip-up night sights built to be used as both your primary sights or as backup sights in place of your optic.
A low-profile, durable flip-up sight built to fold up and stay exactly where you need them until you no longer need them. Quickly adjust, set, and forget the sight pin elevation without tools. Day or night, these iron sights are drop- and shockproof and built for endless rounds of heavy recoil to keep you in the fight.
