Low profile RMR cover plates. Keep your slide looking sleek and professional even without an optic!

Note: This plate is designed for our standard Norsso Glock slide (Spec ops, Gripper, Tiger Claw) profile. This is not compatible with the Piranha slide profile. Click here for Piranha slide compatible plates. 


  • Fits N17, 19, 22, 23, 26, and 27 Norsso slides with a standard RMR optic cut. Any other optic cuts are incompatible with this plate, including the reverse dovetail RMR.
  • This product is not compatible with Glock OEM slides and uses special mounting holes only found in Norsso aftermarket RMR cut slides.
  • Earless design providing a seamless fit with compatible Norsso slides. Low profile chamfers eliminate snagging and catching when using holsters.
  • Made with tool steel for high durability instead of common aluminum plates.
  • Black DLC finish to match standard Norsso slides and for abrasion resistance.
  • Similar weight to a Trijicon RMR to keep a more consistent feel when optic-less.
  • Mounting hardware included.

Use of medium strength thread locker torqued to 15in-lbs is recommended. Fully seat the drive tool to prevent stripping of the drive socket.

Compatible with:
Norsso aftermarket slides only (RMR cut)
