Blue Force Gear
Blue Force Gear Stackable Ten-Speed M4 Two Mag Pouch
Two M4 magazines, and room for a pouch on top.
Stack on top
The front of the slots features single-column MOLLEminus. You can therefore mount other pouches on top of this one, instead of dedicating the surface to a single layer.
Construction
ULTRAcomp and military-grade Ten-Speed elastic. When empty, the pouch lays flat and adds no bulk.
This version holds two M4 magazines or items of similar size. Magazines not included.
