Colt AR-15 A4 Lower Receiver, Engraved, Stripped
The Factory-Correct Foundation for Your A4 Rifle Build
There is no substitute for the real thing. This is a genuine Colt lower receiver, stripped, with “AR-15 A4” engraved on the left side of the receiver and Colt’s QR code applied at the factory. If you’re building a clone of the rifle that served a generation of Marines and soldiers in Iraq and Afghanistan, this is where an authentic build starts.
What Makes This Lower Special
The M16A4 brought the flat-top upper and the rail-equipped rifle to the line infantryman, and Colt’s AR-15 A4 is the semi-automatic civilian counterpart. Colt makes this lower the same way it makes its service receivers: forged 7075-T6 aluminum, machined to mil-spec dimensions, and finished in Colt’s hard anodize. Every dimension is genuine. It isn’t “mil-spec compatible.” It is mil-spec, made by Colt.
The marking is the point. Plenty of builders can put together a 20-inch A4-style rifle on an unmarked lower. Far fewer can put a Colt-engraved “AR-15 A4” receiver at the heart of the build. The crisp engraving reflects Colt’s current production, and the QR code gives you factory traceability that collectors increasingly look for. Together they separate a rifle that looks the part from a rifle that is the part.
Who This Is For
Clone builders assembling an M16A4-style rifle who want the lower to say Colt, because it was made by Colt. Collectors who want an A4-marked Colt lower without paying for a complete rifle. And anyone who prefers the 20-inch rifle’s reach and smooth rifle-length gas system to a carbine.
What You Should Know Before Buying
This is a stripped lower: no trigger group, no pistol grip, no buffer tube or stock. It’s a semi-automatic receiver marked SAFE / SEMI, and it accepts all mil-spec lower components. For a correct A4 profile, pair it with an A2 fixed stock and a rifle-length buffer system. It ships as a firearm and requires transfer through your FFL.
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.

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.
