THIS IS A SERIALIZED FIREARM.  IT MUST SHIP TO AN Federal Firearms License holder.  No civilian exceptions.

A firearm cannot be sent directly to you.  I am sure you know this, but for the fake-news reading this, who might think that a firearm can be mailed to a buyer, I have to reiterate:  A firearm or federal regulated serialized item (like a receiver or suppressor), only a federally licensed firearms dealer may receive such an item.

Note:  California residents, click here for CA compliant processing.  This will also work for New York residents.  We will act on your behalf and instructions to ship to restrictive states, but ultimately, it is your responsibility to know the local and state laws.  We are in Virginia, and cannot, and do not know all the nuances of other states.  If we ship to your FFL, and there is an issue, we cannot accept a return, so please make sure that you know and follow your local and state laws.

Please note our shipping timelines.  We do not ship immediately.  Also, if you choose the free 5-7 day shipping, those orders ship after all other forms of shipping chosen.  Express shipping is given priority. 

Be sure to read our return policy.  While your satisfaction is our primary concern, we are limited in a highly regulated business environment by what we can and cannot do, and the number of local, state and federal regulations.  We do not accept returns for ammunition and firearms, other than obvious defects.  Your gun dealer or transfer agent is responsible for inspection for defects:

THIS IS A SERIALIZED FIREARM.  It must ship to a Federal Firearms License holder.  No civilian exceptions.

Buying and shipping through Charlie’s is easy, but there is some information you need to know. Only a federally licensed firearms dealer may receive a firearm or federally regulated serialized item (like a receiver or suppressor). We cannot ship these items directly to you. Please follow these steps to process your transaction:

1)     Check your state laws to make sure the federally regulated item you want to purchase is legal in your state. Your FFL dealer should be able to give you all of the necessary information regarding your state specific laws. But, if we ship to your FFL, and there is a legal issue, we cannot accept a return. So please make sure that you know and follow your local and state laws.


2)     A quick google search will show you what Federal Firearms Licensed (FFL) dealers are in your area. When you are ready to purchase, contact the FFL dealer you would like to use and get their shipping address. During the check-out, put YOUR address in the “billing” section and the FFL DEALER’S address in the “shipping” section. If you don’t know your FFLs address, that’s okay. You can send the information later.


3)     After check out, make sure to contact your FFL dealer to ensure they will receive your shipment for you (most do this for a small fee, but you should always double check).


4)     Have your dealer send us a copy of their FFL to Charlie’s does not reach to your FFL (MAKE THEM EARN THEIR FEE!!!)


5)     Be patient! In order to ensure we remain compliant with all federal laws, our compliance department is kept separate from our sales and operations team. Please allow a few days for our compliance officer to verify all of your dealer’s documents and ensure all federal laws are being observed. You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.


That’s it! We try to make this process as simple as possible for our customers, but if you are unfamiliar the process or have any other questions, please visit our How to Buy a Firearm page for more details.

California and New York residents please, click here. The process may be different due to state specific laws.

NOTE: The free shipping option does not apply to full rifles, unless purchased with a riflescope.  If you choose free shipping at check-out, we will bill you for shipping later.
