I can prove I'm legally allowed to buy that mag over 10 rnds.

We have not found a service that can provide an automated verification that would be needed to make sure a customer is legally qualified to purchase magazines that exceed the limitations of each state affected. If you know of a service that does that, without requiring the very limited time of our small staff, or exorbitant fees, we'd appreciate the recommendation. If you live in an affected state, you will not be able to purchase said mags from us. Sorry
Please do not provide us any personal documentation regarding your eligibility, as we are not qualified to verify this, nor do we desire to store that sensitive information.
