XS Sights’ Minimalist OR sights (MPN GL-M201P-4) are low-profile backup iron sights built to co-witness with RMR, 507, or ACRO-footprint red dots on compatible Glock models. The blacked-out, serrated rear pairs with a front sight available with or without a tritium insert, so the optic’s window stays clear and usable if the dot ever fails.

Key Specifications

• Fits Glock RMR/507/ACRO-milled models. Covers Glock 17, 19, 22-24, 26, 27, 31-36, and 38.
• Low co-witness height. Lines up with a properly mounted red dot without extra height calculations.
