The ATS Double M4 Stacked Shingle came from requests from units for a hard-sewn shingle style pouch that held two M4/M16 magazines in a single-height configuration.

Awesome double stacked shingle with the elastic cord to retain your mags. When brand new, a little tough slipping PMag's back into place, however it was just out of the packaging and will most likely stretch a little when it gets wet/used. I have no issues at all with this product and it's slim profile makes it perfect to mount onto a PC while still maintaining a flat front/low profile kit.
