Cross Armory RMSc Mount Adapter - Dovetail, 17-4 Stainless Steel, Green Fiber-Optic - Compatible With OEM Glocks

This Cross Armory Rear Sight Dovetail to RMSc Mount Adapter is a precision optics mounting solution engineered to convert standard OEM Glock dovetail slides into a low-profile RMSc-compatible platform without requiring slide cutting. Machined from 17-4 stainless steel and finished in black nitride, the adapter replaces your factory rear sight with an integrated mounting plate while simultaneously incorporating a bright green fiber-optic front sight pre-installed at co-witness height. The dual-sight configuration provides rapid target acquisition and serves as a dependable backup aiming system should your red-dot optic fail. Compatible with OEM (non-MOS) Glock models 17, 19, 19X, 20, 21, 22, 23, 24, 26, 27, 29, 30, 30SF, 34, 36, 42, 43, 43X, 45, and 48-though not compatible with the Glock 44-this adapter accommodates most RMSc-footprint micro red dots, including Swampfox Sentinel, Holosun 407K/507K, SIG Romeo Zero, Shield RMSc, Hex Wasp, and Crimson Trace CT-1550 optics. The package includes installation tools (punch rod and hex wrench) for dovetail removal and installation, eliminating the need for slide modification while maintaining a slim profile suitable for many optic-ready holsters.
