Colt M4 Carbine marked lower. 100% Colt parts, with the QR code on the magazine well. CR serial number, blah, blah, blah.
These are the 2018/19 design and serial number, but production is current year production. We call them 2018/19 as Colt changed their production serial numbers and QR coding at that time. Some might be 2018, some might be 2020, a small number could be 2021, all current production, or production that has been in our warehouse for a while.
Charlie's sources new Colt factory lowers and also "take-offs" from full rifles. This item is a rifle take-off. Not used, only fired at Colt factory for testing. Not eligible for a pistol build.
All lowers are sold no return policy, as we do not accept returns for firearms, unless your FFL advises of damage. Scrapes and scratches are not damage on this lower, that is called "Colt."
Charlie's also offers the 2020 Production Colt M4 Carbine Complete Lower Receiver, which is identical in manufacturer, but has slightly different left magwell markings, and will be more available than the now older production models.
Serial Number Series: CR
QR Code: Yes, left on magwell
Virgin Lower: No, rifle take-off MAY NOT BE USED TO BUILD A PISTOL

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 FFL@CharliesCustomClones.com. 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.
