The Gordon Delta Carbine barrel and Allen Engineering M4 suppressor matched set — the clone-correct front end for a Black Hawk Down / Operation Gothic Serpent "Gordy" carbine build, in 14.5" configuration.
This matched set exists because the tolerances between the Gordon carbine barrel and the Allen Engineering M4 suppressor are unforgiving. The inner sleeve of the clamp collar must fit the barrel journal with virtually no play, and the suppressor alignment depends on barrel threading that is correct to the thousandth. Selling these components separately would leave too much to chance — a barrel that is off by a few thousandths, or a clamp sleeve machined for a slightly different journal diameter, means the suppressor will not align safely. Charlie's Custom Clones, working with Potomac Armory and Allen Engineering, assembles, tests, and alignment-checks every matched set with a Surefire alignment rod before it leaves the shop.
The historical basis for this build is the carbine carried by MSG Gary Gordon during Operation Gothic Serpent in Mogadishu in October 1993. The original rifle used a 14.5" government-profile Colt barrel with an Ops Inc suppressor — a design manufactured in very small numbers for US military special operations. Allen Engineering, which produced most of the original Ops Inc suppressors, has reproduced the M4 suppressor to the same specifications as the early-1990s originals. The brown Gunkote finish is period-correct; a black Cerakote variant is also available depending on current Allen Engineering production runs.
A note on barrel fitment: the inner sleeve of the clamp collar fits so tightly that the raised area from Colt's barrel roll marks must be filed down to bare metal near the threads. Actual barrels are re-finished after fitting. This is a manufacturing reality of matching clone-correct tolerances to modern Colt production barrels.
We built this set for builders who want the real deal, not an approximation. If you already own a Mk12 with an Ops Inc #12-style suppressor and want a Gordon barrel, check out our 12.5" Gordon barrel kit instead. For the full Gothic Serpent build with the correct AEM M4 suppressor, this matched set is the way. Copy that — we'll get it out the door.

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.
