FRBS 4D / 2D Fab Defense & Meprolight Tritium Enhanced Front and Rear Back-Up Sights

Often, we don't really think about backup sights all that much. Sure, we know they're important—should your optic fail, or be damaged, or even unsuitable to the task, you need to have sturdy iron sights that won't run out of batteries—but they are all-too-often put on and forgotten.

Part of the reason for this is likely that backup sights are rudimentary at best. Oh, sure, most are adjustable for elevation and windage, but for the most part, you clamp 'em to the rail, check zero, and never think about them again. Backup sights don't offer anything other than a fallback should the worst happen, so they slide off the radar.

Meprolight's FRBS backup sights look to change that, though. With simple flip-up (and down) operation, these sights are astonishingly simple to deploy and stow, but the real surprise is evident in low or no light conditions. Both the front post and the rear sight contain tritium inserts for rapid target acquisition in darkness.

The FRBS are tritium-enhanced front and rear back-up sights designed to provide the shooter secondary sights in case the primary optics go down.
FRBS sights are advanced, low-profile, durable, tritium-enhanced auxiliary front and rear back-up sights. The sights quickly fold up or down depending on the shooters needs. Sight pin elevation is easily and quickly adjusted without tools. FRBS sights are readily mounted on any 1913 Picatinny rail. Day or night, the tritium makes the FRBS a viable option.
