Rival Arms RARA42G006A Slide Completion Kit .45 ACP Glock 21 Black PVD Stainless Steel

The Rival Arms RARA42G006A Slide Completion Kit delivers a complete set of precision internal components designed to finish out a stripped Glock 21 slide. Each part is precision-machined from stainless steel and finished with a durable black PVD coating, engineered to tight tolerances for a drop-in fit and consistent function. Built specifically for the .45 ACP Glock 21 platform, the components are matched to work together as a complete internal set right out of the box.

This slide completion kit is made for Glock builders, custom shops, and gunsmiths who already have a stripped G21 slide on hand and need every internal slide component in one matched package. The black PVD finish over stainless steel adds corrosion resistance and a clean, low-glare appearance that complements Rival Arms' premium upgrade lineup of barrels, slides, sights, and guide rod assemblies.

Whether you are assembling a custom G21 build from the slide up or refreshing worn factory internals with a precision-matched set, this Rival Arms slide completion kit provides the quality, fit, and reliability expected from a premium .45 ACP slide build.
