Rival Arms Tritium Night Sight Set Glock MOS 17/19 Green White Front Ring
The Rival Arms RA3B231G is a tritium night sight set machined for the Glock MOS 17 and 19 slide profile. The front sight pairs a green tritium vial with a white outline ring for a fast, high-contrast reference in low light or daylight. The rear sight carries a matching green tritium insert, housed in stainless steel with a black nitride QPQ finish.
Key Features
- Direct MOS Fitment — Dimensioned for the raised Glock MOS slide profile; installs without modification, adapter plates, or shimming.
- Green Tritium Front and Rear — Self-luminous tritium vials in both the front and rear sights glow continuously without batteries or ambient light, keeping your sight picture visible in total darkness.
- White Outline Front Ring — The white ring surrounding the front tritium vial creates a high-contrast reference point in daylight or artificial light, speeding up target acquisition when tritium glow alone is not needed.
- Stainless Steel Housings — Both front and rear bodies are machined from stainless steel, resisting corrosion from sweat, moisture, and carry conditions over the service life of the vials.
- Black Nitride QPQ Finish — QPQ (Quench-Polish-Quench) nitriding diffuses into the steel surface to a controlled case depth, producing a matte black appearance with corrosion and wear resistance that does not chip or flake like surface coatings.
- 3-Dot Configuration — One front dot and two rear dots align in the standard three-dot pattern, matching factory Glock sight geometry so no holdover adjustment is needed when switching from OEM sights.
