Not bad - BlackHawk Enhanced Omega M-16/Pistol Mag Holds 2 Each Black 5616PMBK

This was overall a good deal for the money. I Carry an M16 often and this saves me time. It doesn't seem like it will hold up for too long against the abuse I plan on giving it, but since it was not very expensive, it shouldn't be a big deal. Be sure to velcro-in your 9mm mags tight or they will tend to move around a lot. I prefer my regular belt mag holder for regular patrol when I don't need the M16.
Pros: Very light, saves space on your belt
Cons: Not exactly what I was expecting
