Not sure what Dabster means, Beez Combat Sysems is top notch and has an excellent reputation.
Yeah, Maxpedition does the BOGO all the time. The Roly Poly isn't that great as a dump pouch, in that it's a bit shallow, and mags tend to fall out of it if you don't close it.
But for a general purpose stowable pouch, they're GTG.
I think for lo-pro on a duty belt, I'd want the BFG Ten Speed. Very small and flat footprint when not in use.
