AoA Duty Slide w/ RMR Cut For Glock 20/21

Everything You Need, Nothing You Don't!

Our G20/G21 Compatible Duty Slides w/ RMR Cut are precision CNC machined from American 416R Stainless steel, and come ready to accept Glock OEM internals, barrels, and guide rods right out of the box.  Through tighter tolerances, our duty grade slides offer better performance over an OEM slide and will serve you well in your next 80% build or upgrading a stock slide.  Our duty grade slides are upgraded in all the right areas to improve performance without the additional costs associated with windows, ports, or other visually enhancing features.

This slide features an RMR Cut and is ready for your favorite RMR Trijicon or Holosun optic such as the popular 507C micro-optic.  Alternatively, use a RMR Cover Plate (Sold Separately) if you prefer to run your slide without an optic.

Our G20/G21 Compatible Duty Grade slides are unbranded, though manufactured in the same U.S. facility as many products twice the price!

*Note:  The RMRcc has different bolt spacing and will not mount directly to the slide.  Holosun K series are not compatible.  


  • Match grade, tight tolerances that are more specific than factory grade
  • Angled serrations for improved grip and slide manipulation in stressful environments
  • Front and rear side serrations for maximum grip and slide manipulation
  • Offered with unique cerakote patterns for a true custom appearance and corrosive resistance.
  • Compatible with G20/G21 Gen 1-3 OEM and aftermarket parts & accessories.
