Introducing our new rear sight replacement mount, the perfect solution for getting as close to the slide as possible without needing a MOS-ready Glock or cutting. This mount is designed for optimal compatibility with RMS, RMSw, SMS, SMS2 or Jpoint sights and can also accommodate RMSc and SMSc models. The compact design of these sights means they will be narrower than the mounting plate. Installation is easy, simply remove the rear iron sights, slide in the packaged receiver and secure the sight to the mount and receiver with screws.
