How to Adjust the Carnex MRD Magazine Carrier

The Carnex Weapon System features an adjustable MRD (Magazine Retention Device) magazine carrier that allows you to fine-tune the fit, retention, ride height, and angle of your magazine carrier.

Because magazines vary in size and shape, your MRD carrier may require a small adjustment to get the retention exactly where you want it.

Adjusting Magazine Retention

The MRD uses an adjustment screw to control how tightly the carrier holds your magazine.

  1. Insert your magazine into the carrier.
  2. Locate the MRD retention adjustment screw.
  3. Turn the screw clockwise to increase retention.
  4. Turn the screw counterclockwise to decrease retention.
  5. Make small adjustments and test the magazine after each adjustment.
  6. Continue adjusting until the magazine is held securely while still allowing a smooth, consistent draw.

Avoid overtightening the MRD. The goal is to have enough retention to securely hold the magazine during normal movement without making the magazine unnecessarily difficult to remove.

Adjusting Ride Height and Cant

The Carnex magazine carrier also allows you to adjust the ride height and cant (angle) of the carrier.

Changing the position of the mounting hardware allows you to move the magazine higher or lower and change its angle. This lets you fine-tune the Carnex system for your body type, preferred draw position, comfort, and concealment.

After making an adjustment, put the Carnex on and test the position before making additional changes. Small adjustments can make a significant difference in how the system carries.

Fine-Tune Your Carnex

There is no single retention or carrier position that is perfect for everyone. The Carnex MRD magazine carrier is designed to give you the ability to adjust the system to your preferences.

Take a few minutes to experiment with the retention, ride height, and cant until you find the combination that provides the best balance of security, comfort, concealment, and access.

The MRD system is designed specifically to provide adjustable magazine retention, allowing the carrier to accommodate a variety of magazine types while letting the user control the amount of tension.
