Magazine Capacity Restrictions
Atlantic Firearms follows all state regulations regarding the sale of high capacity magazines. Due to multiple states and cities now enforcing various magazine restrictions and more coming we will not ship magazines that are restricted in your area with firearms to the states listed below. If the mag that comes with the firearm is not legal in your state or city the magazine will be removed from the shipment. We do not offer custom magazine requests to swap out, ship to another state, refund, pinning of mag, substitutions, dealer approval or other. Hopefully we will see changes to these laws and violations to our second amendment rights. We apologize for this but we simply cannot accommodate each and every magazine request with over 30 different laws, regulations and restrictions impacting states, cities and local jurisdictions throughout the country. It is the customers responsibility to be informed of your local laws prior to completing your purchase. Atlantic Firearms is not responsible for any issues that may arise with magazines shipped to you or your FFL dealer that may not be legal in your area due to a change in current laws.
