Crye Precision R-Series M4 Side Pouch: Holds one M4 Magazine to Command fast mag changes.
- The Crye R-SERIES M4 Side Pouch is an advanced, versatile solution for carrying a single M4 magazine, offering a unique take on the traditional mag pouch. Its primary benefit is providing fast, reliable magazine access in dynamic environments, which is achieved through its key differentiator: a pre-molded shape for easier insertion and a direct Velcro® side-attachment system for seamless plate carrier integration. Operators need this pouch to gain a tactical advantage through more efficient reloads and improved gear management in critical situations.
- Ambidextrous and Adjustable Fit: The pouch is engineered with a reversible, ambidextrous design that allows it to be easily configured for left, right, or bottom mounting based on operator preference. An adjustable strap lets you customize the magazine's ride depth, ensuring a secure, tailored fit for unimpeded access.
- Rapid Velcro® Attachment: This system bypasses traditional MOLLE weaving, featuring an innovative Velcro® side connection that allows the pouch to be quickly and securely affixed directly to the front of a plate carrier. This streamlined attachment method is designed for simplicity, speed, and a low-profile fit.
- Enhanced Retention Hardware: It features a unique chord lock and pull tab hardware combination that creates a positive grip and reliable cord retention. This system is purpose-built to facilitate efficient, fast magazine changes when seconds are critical.
- Durable, US-Made Construction: The pouch is built for superior quality and ruggedness using high-quality materials sourced and manufactured in the USA. Its pre-molded shape is designed to hold up under stress and makes inserting magazines faster and easier in high-pressure situations.
What are some common accessories to add to the R-Series M4 Side Pouch?
Core Platforms & Mounting Solutions
- Crye Precision JPC R-SERIES™: This minimal armor carrier is the core of the assault configuration and is designed for maximum mobility and weight savings. It directly integrates with the R-SERIES™ M4 Side Pouch via a dedicated channelized Velcro® side slot, allowing for quick, secure attachment without the need for traditional MOLLE weaving. This creates a streamlined system that keeps both armor and ammunition close to the body.
- Crye Precision R-Series Harness Adapter: This adapter is the base component for creating minimalist chest rig configurations. It enhances the versatility of the M4 Side Pouch by allowing it to be mounted on a lightweight harness system for JUMP or RECCE loadouts. The adapter features its own side Velcro® attachment points, providing a seamless mounting surface for the M4 Side Pouch when a full plate carrier is not required.
System Balancing & Load Carriage Expansion
- Crye Precision R-Series Zip-On Pack: This pack provides scalable load carriage that attaches directly to the JPC R-SERIES™ or can be configured with the Assault Harness. It allows an operator to balance the weight of front-mounted items, such as magazines carried in the M4 Side Pouch, with hydration, communications, and other mission-essential gear on the back. Its multiple attachment points and conversion capabilities make it a versatile tool for tailoring your loadout to shifting mission profiles.
- Crye Precision R-Series Drop GP Pouch 8x5: This versatile general-purpose pouch adds accessible storage below the main platform. It attaches to the slip pocket on components like the JPC R-SERIES™ or the M4 Jump Flap, complementing the specialized role of the M4 Side Pouch by providing space for medical supplies, tools, or other sensitive items. An elastic loop on the bottom provides a secure area for a tourniquet.
Communications & Electronics Integration
- Crye Precision R-Series Radio Side Pouch: This pouch uses the same secure Velcro®-in side attachment system as the R-SERIES™ M4 Side Pouch, allowing for a streamlined fit to the vest or harness adapter. Its ambidextrous design enables an operator to place a radio directly opposite their M4 Side Pouch, creating a balanced, symmetrical loadout for efficient access to both reloads and comms. The design fits PRC 163, 152, and 148 radios and allows for easy battery changes without removing the radio from the pouch.
