Product Description
Mount a Shield RMSc or SMSc optic to your Glock 21 without milling the slide. This low-profile slide mount replaces the rear iron sight with a slide-in rear sight and mounting plate, sitting flush with RMSc and SMSc optics for a clean fit. It will also accept the standard RMS, SMS, SMS2, and JPoint sights with a slight width overhang. The RMSw can fit, but may not seal because the plate is narrower than the RMSw and its gasket.

- Flush fit with Shield RMSc and SMSc micro red dot optics
- Also accommodates RMS, SMS, SMS2, and JPoint (with minor width overhang)
