Crye Precision R-Series™ Harness Adapter | Modular Plate Carrier Base System

The Crye Precision R-Series™ Harness Adapter is the foundational piece in the R-SERIES™ modular system. Designed to offer maximum scalability, this harness adapter allows you to configure your loadout for slick low-profile wear or fully kitted missions. The front accepts Crye’s detachable flaps, while the rear features a stretch pocket that can carry either a ballistic plate or additional mags using the R-SERIES™ M4 Mag Retainer.

Pair it with the R-SERIES™ Assault Harness and Plate Cover to build out a minimal plate carrier or use it as a streamlined placard base for chest rigs. Built from US-made materials, this adapter is rugged, versatile, and ready for real-world use.

If you’re running Crye, this is the piece that pulls your whole system together.
