BROWNELLS RMR CUT SLIDE FOR GLOCK®21 GEN 3 STAINLESS STEEL NITRIDE

Integral Red Dot Sight Mounting Slot, Plus a Ton of Custom Features!

The limited production Brownells Brown RMR Slide for Glock® 21 Gen3 pistols features a pre-cut slot for easy, secure, low-profile mounting of a Trijicon RMR or Holosun red dot sight. Up front, there are distinctive, cocking serrations that aid in manipulating the slide to check the chamber or clear a jam. And we’ll admit it: the serrations just look cool, too. All RMR Slides also have standard Glock® factory front and rear sight dovetails for “iron” sights. To get proper co-witnessing with the RMR, you will need to also install suppressor-height iron sights.

A Brownells RMR Slide is the ideal upgrade for your factory Glock® 21 Gen3 OR the perfect “top half” for a brand-new custom gun build.

Fits Gen3 Glock® 21 pistols & clones

Built-in Trijicon RMR mounting slot

Also accepts Holosun HE508T, HS507C & HS407C red dot sights

Factory front/rear iron sight cuts, too

Machined from corrosion-resistant 17-4 stainless steel billet

Each RMR Slide for Glock® starts life as a billet of 17-4 stainless steel that is machined to Glock® factory specifications inside, so it’ll accept factory or aftermarket barrels and internal parts. Each slide is heat-treated to Rc 41-44 on the Rockwell C scale for added surface hardness and wear resistance.

Brownells Gun Tech™ Note: Channel liner required for these slides. Channel liner is a press fit and requires a tool to install. We recommend #777-100-017.
