The BDS Tactical Stacker Subload is made to holds up to four government issue magazines. There are 3 rows of PALS webbing on the front of the magazine pouch for attaching additional BDS Tactical Gear modular equipment. The lids on the magazine pouch are fully adjustable / removable and secure with both hook and loop fastener and snaps. Another great feature on the stacker sub load is that the base of the sub load doubles as a 7"x 7" pocket for storing miscellaneous items such as empty magazines, etc.
