60RD M4 Collapsible is designed to allow the operator to carry two M4 style magazines securely in a pouch as per our classic 60RD Velcro. 
By removing the MOLLE from the side and introducing an elastic band to hold the mags tight, this pouch allows the operator to carry one mag securely in the pouch when the other is removed. The elastic prevents the slapping sound usually associated when carrying a single mag in a double mag pouch.
We can make to order in other patterns but first call us to discuss availability and lead time.
