Meprolight FRBS AR-15 Flip-Up Backup Sights - Green Tritium Front / Blank Rear

The Meprolight FRBS is a self-illuminated flip-up backup sight set designed for the AR-15 platform. Built by Meprolight in Israel, this rugged set pairs a green tritium front sight with a blank rear sight, giving the shooter a clean, uncluttered sight picture for rapid target acquisition in any lighting condition. The premium Swiss-made tritium vial glows continuously without the need for batteries or switches, making the FRBS a true "always on" aiming solution for low-light and nighttime use.

Constructed with an all-metal housing in a black aluminum finish, the FRBS flips up securely when needed and folds down flat to stay out of the way of a primary optic. The blank rear sight is intentionally featureless so it does not obstruct the view through a co-witnessed red dot or holographic sight, while the bright tritium front post draws the eye quickly in dark conditions. Manufactured by Meprolight to ISO and MIL quality standards, the FRBS is a reliable backup aiming system for defensive, duty, and recreational AR-15 rifles.
