The Double 762 is designed to hold two 20 round 762mm magazines. It is specifically sized for thicker magazines, so most polymer mags will fit. It is laser cut from Cordura laminate making the pouch very abrasion resistant while still being lightweight. In addition to the mil-spec Velcro closure, there is a shock cord tension system to help retain the magazines. On the bottom of the pouch there is a laser cut hole for drainage. The back of the pouch has a built in mounting system, compatible with PALS webbing. Weighs only 64g.
