Crye Precision R-Series™ M4 Jump Flap | Streamlined Modular Chest Rig Flap
The Crye Precision R-Series™ M4 Jump Flap delivers streamlined performance with mission-adaptable flexibility. In its base form, it secures three 30-round M4 magazines in a low-profile flap, complete with 1" side loops for retention during dynamic or airborne operations. A hidden bottom slip pocket adds utility, offering storage for sensitive items or integration with Velcro® side pouches compatible with the JPC R-Series™.
But it doesn’t stop there. Add the R-Series™ Assault Harness and Harness Adapter to convert it into a lightweight JUMP chest rig. Pair with the R-Series™ Plate Cover and Zip-On Pack Adapter for a complete RECCE-style loadout. From slick to full kit, this flap adapts to your environment and mission profile.
Why We Love It
This isn’t just a mag flap, it’s a foundation for a modular loadout system. Whether you’re going low-profile or scaling up to a recon-ready plate carrier, the Jump Flap is the starting point for total kit flexibility.
