Geissele
The Clone Correct URG-I M4 Carbine Rifle Kit brings you to the forefront of performance by mating the URG-I Upper (currently fielded by USASOC) with a Colt M4 Lower. Field tested and proven, this 5.56 NATO chambered, 14.5” carbine is assembled by Potomac Armory in the USA. The Geissele SMR Mk16 brings you unparalleled M-LOK modularity and ergonomics. Potomac Armory includes the Geissele 2-stage SSA match trigger, Colt upper and lower receivers, FN military mid-length barrel, Colt BCG and lower parts, Geissele's Airborne Military URGI charging handle in DDC, a Surefire SOCOM flash hider and Knights Armament steel M4 micro folding back-up sights and a B5 SOPMOD stock.
This is a no tax stamp 14.5" rifle, as the flash hider is pinned and welded.
The original carbine was a special release by Geissele in late 2020, but was a one-time build. At that time, Geissele was featuring the Daniel Defense mid-length gas barrel and Surefire SOCOM 4-prong flash hider. This build is considered by many to be an upgrade, as it uses the very popular Surefire SOCOM Warcomp 3-tine flash suppressor and a carbine gas system. Both accept currently manufactured Surefire SOCOM RC2 and Mini-2 suppressors. We realize that some collectors would like to have the Surefire SOCOM 4-prong, but it is becoming harder to source, and the Warcomp is universally agreed to be an improvement in performance, but you have your choice of either great flash hider.

Manufacturer's model was 08-350 before being discontinued.
Note: The Surefire Warcomp is the correct muzzle device. Residents in states that ban flash hiders can request a Surefire brake at no additional charge, but expect additional armorer time.
Note: Pictures do not reflect the Knights Micro BUIS.
Note: This is a rifle kit. The upper will ship to your home and the lower to your local firearms dealer. The parts came to Potomac as an upper and lower, and will ship to you as an upper to your home and a lower to your local gun dealer. We call this a rifle kit. The upper is fully assembled, and the lower is fully assembled, but we are not shipping a rifle to your dealer. You will be required to connect the upper with the lower.

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.
