Dump pouches are one of those things that may not seem necessary at the time. But when you’ve got one, you constantly use it! Dump pouches are not only for stowing empty magazines – most of the time they’re used for all sorts of other things. Full mags. Drinks. Snacks. Tape. Sharpies. Souvenirs. Evidence. Etc.
