This backup plan is always in sight.
The Mepro FRBS is a tritium-enhanced set of sights – two or four smaller tritium vials, depending on the model, are firmly inserted on the large aperture side of the rear sight.
The self-illuminated front and rear backup sights are designed to provide the shooter with secondary sights in case the primary optics go down. In addition, the Front Sight post elevation is easily adjusted without tools.
Day or night, the tritium makes the Mepro FRBS a viable option.
The Mepro FRBS is an advanced, dual aperture, durable and low-profile auxiliary tritium-enhanced set of backup sights. 4 tritium vials are firmly inserted in the rear sight, and one tritium vial is inserted in the front sight. In addition, the Mepro FRBS self-illuminated backup sights are designed to provide you with secondary sights if the primary optics go down. You can also use it as primary sight.
HIGH DURABILITY: The advanced Mepro FRBS sights are made of strong, high-grade polymer and metal parts and are highly durable. Quickly and easily flip them into position when needed. Maintenance-free can be mounted directly with no modifications using a 2.5mm Hex key (provided). The instant spring-locked deployment mechanism will not slip, break or deform. Sight pin elevation is easily adjusted without tools and the windage adjustment, with positive detent locking, does not require tools.
HYPER-BRIGHT FRONT: The MEPRO FRBS Hyper-Bright™ Front Sight offer the most reliable illumination for day or night. Mepro Hyper-Bright™ front features an extremely bright fluorescent contrast orange colored ring during daytime. The tritium source appears green in low light and nighttime.
ALWAYS ON: Premium grade green Swiss-made Tritium vials on the front and rear sights allow for low light and nighttime conditions. No batteries, no switches – always on always ready 24/7 for 12 years. The nighttime illumination is designed bright enough to see them but not too bright to impact sight picture.
