Crye Precision R Series M4 Jump Flap | Modular Chest Rig Placard for M4 Magazines

Built for Modular Loadouts and Scalable Chest Rig Systems.

The Crye Precision R Series M4 Jump Flap is a low profile chest rig placard designed to carry M4 magazines while serving as the foundation for a fully modular tactical loadout. Developed to give end users a streamlined way to run essential rifle mags with the ability to scale up into a full chest rig or plate carrier system, this flap solves the problem of being locked into a single configuration.

Whether you are building a minimalist setup for low visibility operations or expanding into a full RECCE loadout, this modular mag placard adapts to your mission. Designed around Crye’s R Series ecosystem, it integrates seamlessly with chest rigs, plate carriers, and zip on pack systems for maximum flexibility.

Streamlined Storage with Expandable Capability

In its base form, the Jump Flap securely holds three 30 round M4 magazines in a clean, low profile layout. Side loops provide additional retention for dynamic movement or airborne operations, keeping your mags locked in when it matters.

A hidden bottom slip pocket adds extra functionality, allowing you to store sensitive items or attach hook backed pouches for expanded admin or utility storage. Built for integration, this flap can convert into a full chest rig with the R Series Assault Harness and Adapter, or scale into a complete plate carrier setup with compatible components.

Why We Love the Crye R Series M4 Jump Flap:

This is not just a mag flap, it is a starting point for building a smarter kit. It gives you the ability to run slick when you need speed and simplicity, but also scale up without replacing your gear.

It is especially valuable for users who want one system that can flex between training, range days, and real world applications. Instead of buying separate setups, this lets you build once and adapt as needed. Clean, efficient, and purpose driven, it fits right into modern modular loadouts.
