How do you guys interpret the following rule concerning rifle mags in limited classes?
only traditional double stack mags allowed.  (cinched mags must be offset a minimum of 2 inches to avoid being considered an external supporting device)

I have an Arrendondo mag coupler on two Pmags that I am wondering about The mags are offset about an inch, but if you measure outside of mags, they are about 2.25 inches across.
What do you think, legal or not?
