The Colt Commando CR6933 / LE6933 — an 11.5" short-barreled 5.56 NATO M4-pattern carbine from Colt, built on the Colt-military production line and sold as an NFA-registered SBR.
The Colt Commando 6933 is the civilian CR6933 and law-enforcement LE6933 variant of Colt's compact 11.5" M4-pattern carbine — the short-barrel platform that law enforcement entry teams have run since the 2000s, and the platform the US Army's Mk18-family carbines traces to at the receiver and trigger group level. The Commando profile trades the M4's 14.5" barrel for an 11.5" barrel with a carbine gas system: shorter overall length, heavier handling forward, and enough 5.56 velocity to matter inside the range a carbine is actually used at.
Every 6933 leaving the Colt line is a real Colt-military component rifle — the upper, lower, barrel, and most small parts carry Colt rollmarks and a CAGE code where the contract calls for one. Receivers occasionally come off the line without the CAGE stamp; this is a Colt production variance, not a sign of an aftermarket rebuild. The 11.5" Colt barrel is the same profile and finish as the Colt military SOCOM barrels in the 14.5" rifles — chrome-lined, phosphated, and marked with the 5.56 NATO chamber and 1:7 twist designation.
The front sight base is the correct F-height for an M4-pattern flat-top upper, and the gas port is cut for carbine-length gas on the 11.5" barrel. Running a suppressor on an 11.5" Commando is the shooting-school default configuration and why the platform reads as a door-kicker; the short barrel plus a compact 5.56 can keeps overall length close to a standard M4 while adding suppression.
Stock hardware ships as Colt delivered it: a 4-position receiver extension and a standard M4 stock. Most units have the P&S CAGE code on the stock; some carry both P&S and Colt CAGE codes; a small share ship without markings. This is Colt factory variance, not a quality difference.
NFA-regulated Short-Barreled Rifle (SBR). Available to law enforcement agencies on department letterhead; available to individuals as an NFA transfer with an approved Form 4. Verify your state and local law before ordering. Charlie's compliance team will walk the transfer through end-to-end; expect to hear from us within 3–4 business days after the FFL/SOT paperwork lands.
For builders looking to extend the Commando with program-correct rail hardware, Charlie's stocks the Knight's Armament M4 RAS that pairs to this upper. We keep Commandos in stock when we can — reach out and we will square you away on the transfer.
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.
