This AR-15 magazine carrier is designed to ride below your belt but above your thigh. This location is ideal for easy leg movement so as not to encumber running, crouching, or crawling on the ground. It holds three 30-Round AR-15 magazines, evenly distributing the weight and feel of the load. The cover flaps have a velcro-durasnap combination closure for outstanding positive control of the magazines. Used by top competitors in 3-gun shooting and ideal for self-defense. I keep mine loaded and ready in my safe next to my AR-15!
