AoA Duty Slide w/ RMR Cut For Glock® 21

Everything You Need, Nothing You Don’t!

Our G21 (45 ACP) Compatible Duty Slides w/ RMR Cut are precision CNC machined from Premium American 17-4 Stainless steel and come ready to accept Glock® OEM internals, barrels, and guide rods right out of the box. Our duty-grade slides offer better performance over an OEM slide through tighter tolerances and will serve you well in your next build or upgrading of 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 an RMR Cover Plate (Sold Separately) to run your slide without an optic.

Our 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. The Holosun K series is not compatible.

Features:

  • 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 G21 Gen 1-3 OEM and aftermarket parts & accessories.

Our “Arm or Ally” branded products are manufactured in the same facilities and to the same standards as many well-known, high-end AR brands.
