I was incorrect in my earlier reading that only a manufacturer can do it, as 18-12-302(3)(a) includes "... or any licensed gun dealer, as defined in 12-26.1-106(6) .... " in addition to the manufacturer of large capacity magazines.
You could also legally take the mags out of state yourself, and then transfer them to someone else while outside of Colorado, since there is no federal regulation on the possession or transfer of magazines.
