Bought two of these to carry mags vertically, chest-high on a MOLLE vest. They work GREAT for that application, but there are a few things to be aware of:
- The fit is EXACT. So, it is not super easy to replace (an empty) one back into the holder without looking at it (and maybe getting tagged while doing so because you aren't watching your opponents). Just takes a little practice to do it only by feel.
- They are not compatible with the Worker 15-round mags because the base on the Worker mags is squared off (and thus won't fit at all)
- You still need MOLLE straps or some other attachment method to actually attach these to a MOLLE vest or pack
- There is no positive retention for the mags; gravity only. So, if you mount them horizontally, they can easily fall out while you are moving.
- On the PLUS side, they are retained "balls up," so if you scavenge rounds off the ground during play, it is easy to shove them into the top of an empty mag as you go and keep your mags topped off. Again, with a little practice this gets pretty easy.
