Rival Arms RARA42G005A Slide Completion Kit for Glock 20 - Black

Building a reliable Glock 20 starts with precision parts that work together as a system. The Rival Arms Slide Completion Kit for Glock 20 is designed to eliminate the guesswork of sourcing individual components—everything you need to assemble the internal slide workings comes in one package. This kit handles the details so you can focus on the build, giving you a finished slide that's ready for a barrel, guide rod, and lower to become a complete firearm.

Rival Arms engineers these kits with tighter tolerances than factory Glock specifications. Key components undergo CNC machining from solid stainless steel billet stock, and select parts receive a low-temperature vacuum PVD coating for durability against wear. Every piece is individually hand-inspected before it ships, so you're starting your build with components that meet exacting standards. No gunsmith skills required—assembly is straightforward enough for anyone comfortable with basic firearms maintenance.

Whether you're a Glock 20 enthusiast building a custom 10mm or upgrading your existing gun, this kit consolidates the slide internals into one purchase. You get all the firing, extraction, and retention components needed, eliminating the hassle of chasing down individual parts across multiple suppliers. Once your slide is complete, you're just a barrel, guide rod, and lower assembly away from a finished firearm ready for the range or field.
