The Rival Arms Slide Completion Kit for the Glock 20 (brand part no. RA-RA42G005A) puts every internal part a build needs to finish a slide in one box, machined to tighter tolerances than factory Glock parts. Select components are CNC-machined from solid stainless steel billet and finished with a low-temperature vacuum PVD coating that creates a durable barrier against wear, and every part is individually hand inspected for accuracy before it ships. Instead of sourcing a striker, extractor, and a half-dozen small springs individually, a builder gets everything needed to complete the slide’s internal workings in one kit, no gunsmith required, then just adds a barrel, guide rod, and finished lower for the range.
