Rival Arms RA4A231G Green Tritium MOS Night Sights

Rival Arms RA4A231G in-line MOS night sights provide green tritium illumination for low-light sight alignment. The set uses an orange-outline front sight, a white-outline rear sight, and a snag-resistant steel frame designed for MOS slides and slides with a mounted optic.

The rounded rear notch and contrasting front sight support fast, clear alignment in daylight while the tritium elements remain visible in reduced light. The supplied product data identifies compatibility with Glock MOS configurations, including double-stack 9mm Glock models.
