I have looked around but have not seen one?
Great find! Elbow grease and stretching??? I wonder if they were heated up a little that it wouldn't be as hard to do?Went poking around on ARFCOM looking for some more info since I would kinda like to slap a few of my mags together as well (too many irons in the fire these days).
Here is a link to a thread that pictures two PMAGs with the Arredondo couplers. Apparently it takes some doing to get them on, but they work and lock up solidly.

Also mentioned the ProMag couplers working on the PMAGs as well.
The real question is can you wear it on your hip like the IDF babes do?I hate mag couplers because they are too thick to grab, pinch the mags and many other common short comings of conventional strap systems.. This coupler was designed to feel like a single mag, and we did it. There is not doubt this coupler is the most secure, easiest to grab and change of ANY coupler I've ever seen. We scrapped a bunch of designs and when we hit this one, it was perfect.
Of course we will fine tune the lines and angles to make it look like part of the magazine, but this should give you a good idea of what we will have available very shortly.
