If you've ever fought with wet cardboard ammo boxes in the bottom of your pack during a rainy match day, or tried to stick a big plastic box of your reloads in your backpack to bang around and get broken then you already understand what the big deal is. The 40/40 Ammo Holder (plus the couple loaded mags you have on hand) finally provides a secure and quiet way to tote enough ammo for a day of match shooting in all conditions. Opposing Velcro on the back of each panel lets you keep two halves together for a match day, just take half for a quick range trip, or stick these on the loop Velcro fields common to many packs and cases. This is one of those solutions that you instantly love onc Mfg: Armageddon Gear
