In states that have so called "high-cap mag" bans, typically they forbid all of possession, manufacture, and commerce related to them. However, some states do allow grand-fathering of these mags for strictly possession, so that it may be legal to actually own such mags after those laws went into effect, within the state.
For states where that is the case (i.e., legally possessing a "high-cap" mag in such a state), can those individuals engage in commerce related to those mags they own with out-of-state customers? Meaning, they are not selling nor advertising nor marketing those mags for sale to individuals within their ban state, but rather perhaps selling them over the web to only out-of-state customers?
Similarly, for both those same "high-cap" mags and parts that make so-called "featureless & compliant" weapons into "assault weapons", can they be housed by businesses within such both "AWB" and "high-cap" mag ban states for sale exclusively to out-of-state residents?
In a nutshell, what I'm asking plainly is if that kind of specific commercial activity for these items is legal in ban states if their sale is legal to out-of-state areas or non-state residents residing in other states (not: non-state residents within the ban state).
