Magazine Retention with the MRD

The added length of the carrier helps conceal a longer magazine by getting more of the magazine below the belt. This feature helps prevent the magazine from tipping out and away from the waist, thus reducing "magazine print".

The smooth back and rounded edges help reduce hot spots and provide a flat, comfortable surface suitable for adding Moleskine or foam wedges (not included). 

The ambidextrous design will allow you to carry the magazines facing forward or back, depending on your personal preference, at any position inside the waistband.

The design of this carrier allows adjustability to the height and cant, up to roughly 20 degrees.

Formed from .080" Thermoplastic for durability

Made and assembled with pride in the USA
