When putting these into existing pouches they do well so you don't have to buy a new pouch system for your carrier or belt setup. They hold the pockets open do they don't velcro shut when empty. I used the long version so it keeps them open for re insertion. Works well but took a little bit for me to get used to it. I used it for both 5.56 and 7.62 pouches and it turned out great.
