Daniel Defense
Looking to take your shooting game to the next level? Check out the DD4 RIII-S tactical ready SBR from Daniel Defense. With an optimized 11.5” short barrel, the DD4 RIII-S Rifle is built for the modern shooter. The high-quality upper receiver group is perfect for anyone who demands the very best in terms of performance, accuracy, and reliability, and brought to you by one of the better battle-hardened rifle makers: Daniel Defense, which is known for performance and durability.
The ambidextrous DD4 RIII AR15 style rifle is designed to satisfy the needs of both right- and left-handed shooters in popular shooting sports and for tactical and defensive applications. Its fully ambidextrous lower allows a shooter to operate the bolt catch, safety selector, and magazine release without having to move or remove their dominant hand from the rifle’s grip, while its GRIP-N-RIP Charging Handle is fully ambidextrous as well. A 10.5 inch lightweight RIS III rail—modeled after the revolutionary RIS II two-piece handguard developed for SOCOM—features M-LOK attachment for lighter weight, and a refreshing modern look. It surrounds an 11-1/2 inch Cold Hammer Forged Government Profile barrel, and a carbine gas system. This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip.
Unmatched Performance and Durability in a Short Barreled Package
With its precision engineered components and rugged construction, the DD4 RIII-S rifle is the perfect choice for serious shooters looking for a personal defense rifle, or a truck gun, or just want something maneuverable and tactical. Featuring a Cold Hammer Forged Government Profile barrel with a Daniel Defense Flash Suppressor, a GRIP-N-RIP Charging Handle, and a fully ambidextrous lower receiver, this rifle is designed to deliver exceptional performance in any situation, and is clearly a modern upgrade of Daniel Defense heritage in tactical rifle manufacturing.

Premium Materials and Construction
Whether you're a seasoned pro or just starting out, the DD4 RIII-S Upper Receiver Group has everything you need to take your shooting to the next level. With its lightweight RIS III rail and M16 profile bolt carrier group, this upper receiver group is engineered for maximum accuracy, durability, and reliability. The lower receiver is a great match with fully ambidextrous settings that are the envy of much higher priced brands. And, we at Charlie's could not help but notice the feel of the proprietary grip. Holding the rifle just feels good.
Featuring a 10.5 inch lightweight RIS III rail, modeled after the revolutionary RIS II two-piece handguard developed for SOCOM, which features M-LOK attachment for increased versatility.
So, how is this rifle different from the Mk18, Mod3, also known as the Block 2 CQBR, URGI? There are a number of similarities. The next generation of Mk18 also features an 11.5" barrel. The 11.5" barrel has come to be known as very forgiving in which ammo it is fed, and a very smooth shooting rifle. The Mk18 now features a Geissele Mk16 rail, which is M-LOK and similar the RIS-II rail. Both are very good shooting rifles. The Mk18 is designed to be shot suppressed, while the RIII-S has the option, and with the flash hider not being pinned to the barrel, it can be removed and a different muzzle device attached. We love the DD grip. Does that count?

You may have found us by looking for Daniel Defense rifles or the new RIII SBR or parts, and that is awesome. Charlie's specializes in military correct rifles for shooting enthusiasts, as well as for military and law enforcement. We are a small business based in Virginia, and our Potomac Armory is a licensed firearms manufacturer and registered DOD contractor and law enforcement dealer. In a few short years, our consumer brand, Charlie's Custom Clones has grown to be the leading brand for shooting enthusiasts who are looking to increase their proficiency and their armament collection with military rifles and the hobby of clone building, which is just another way of saying that our customers want to buy or build a military correct rifle, largely as collectors, but also as active operators. The word, "Clone" in our name scares people that think we have fake products. We do not. Nothing can be further from the truth, as to have a clone rifle is to have as exact a copy of an actual military issued weapon as a civilian possibly can have.
In addition to great combat rifles, we carry a large selection of both military correct suppressors, and popular commercial suppressors. We are a Daniel Defense dealer and Potomac Armory is an OEM manufacturer. Charlie's directly resells DD manufactured parts, uppers, barrels rails, and full rifles. We are proud to carry the Daniel product line, and DD has a fantastic reputation as one of the quality AR style manufacturers, with a military style. Potomac Armory uses the barrels and rails to build military correct clone uppers and rifles. CCC curates our offering of DD products, to fit our customer lifestyle, but if you are looking for something from DD that we do not carry, let us know. Most likely, if it is current production, we can get it for you in short order.
We have online chat during business hours, in addition, you can contact us with product questions on Instagram and Facebook at @charliesclones as well as email and phone support. Let us know how we can help you, and help to make your shooting sports ambitions come true. Thanks for stopping in.

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.
