Yes, you can buy a gun magazine in another state. You can also buy guns and ammunition in other states. There are no federal laws that prohibit this, although some states may have their laws banning the purchase of certain types of firearms or ammunition. So, it depends on what state you’re in and what type of gun magazine you’re trying to purchase.
For example, California has laws restricting the sale of high-capacity magazines (ones that can hold more than 10 rounds of ammo). So if you’re trying to buy a high-capacity magazine in California, you’ll likely have to do so from an out-of-state retailer. But if you’re just looking for a regular gun magazine (one that holds 10 rounds or less), you should be able to find what you’re looking for in most states.
There are a few things to keep in mind when buying gun magazines from another state, though. First, make sure you’re familiar with the laws of the state where you’ll be making the purchase. Second, it’s always a good idea to check with the retailer beforehand to see if they ship to your state. And finally, when you do make the purchase, be sure to have the magazine shipped to an address where it’s legal for you to receive it (again, depending on the laws of your state).
As long as you’re familiar with the laws and regulations of the state where you’ll be making the purchase, and as long as the retailer ships to your state, you should be able to buy a gun magazine from another state without any problems.
I hope this answers your question!
