Glock, Oem Fixed Rear Sight 6.9mm, Polymer White Insert

The Glock OEM fixed rear sight 6.9mm poly brings a no-nonsense sighting solution for anyone running Glock pistols from full-size service frames to heavy-hitting hunting and duty platforms; molded from durable polymer with a high-visibility white contrast insert, this rear sight speeds sight acquisition in low light and under stress without adding weight or snag points. Designed to fit all Glock models except the slim G42 and G43, it carries a standard height on G20, G20SF, G21, G21SF, G29, G29SF, G30, G30SF, G30S, G31 and G32 including Gen4 variants, so you can swap into older or Gen4 frames and maintain the same sight picture you train with. As an OEM Glock part, the sight maintains factory dimensions and co-witness relationships for those using aftermarket optics or suppressors on compatible platforms, and its fixed rear profile offers rock-solid zero retention for range work, field use, and classes where reliability matters. If you're upgrading worn factory sights or setting up a backup iron sight system for hunting or patrol use, this 6.9mm Glock polymer rear sight provides consistent alignment, easy maintenance, and the tried-and-true fitment Glock owners expect, making target transitions faster and follow-up shots more dependable.
