A factory Daniel Defense DDM4 PDW 7" 300 Blackout upper receiver group — a new take-off from a factory-assembled PDW SBR, built around the MFR XL rail for under-the-rail suppressor clearance.
The Daniel Defense DDM4 PDW is a 7"-barreled 300 Blackout short-barreled rifle built around Daniel Defense's MFR XL handguard — a 6" M-LOK rail with a 1.61" internal diameter. That internal diameter is the reason the PDW exists as a distinct product: a standard .30-caliber suppressor (an OD of roughly 1.5" or less) fits inside the rail when the blast comp is removed and a direct-thread can is installed. The suppressor's body nests alongside the barrel instead of hanging off the front of it, which is what gives the PDW its unusually compact suppressed length.
This upper is a factory take-off — Daniel Defense assembles the complete PDW SBR, and Charlie's receives the complete upper pulled off the factory rifle during disassembly at Potomac Armory. It is not a hand-build; it is the same upper assembly that shipped on the complete PDW. The upper receiver is forged 7075 military-grade aluminum with a hardcoat Type III black anodize, matched to a forged 6061-T6 MFR XL rail with the same finish.
With the linear blast compensator installed, the upper runs supersonic and subsonic 300 Blackout without special tuning. To suppress, remove the blast comp and install a direct-thread .30 cal can in the 1.5"-or-less OD range — the shorter, simpler, older-generation .30 cans are a better fit for the MFR XL's internal diameter than the newer, thicker titanium designs. 300 Blackout is easy to suppress and does not demand a modern flow-through can; a classic direct-thread .30 suppressor does the job and keeps the overall length short.
Supply note: these factory take-off PDW uppers move fast. If you can add it to the cart, we have it — but for every four we receive, we typically have eight people on the notify list. Don't hesitate if you see it in stock. FDE and Cobalt Cerakote variants are also available and tend to be more consistent inventory. Photos show the complete rifle and handstop configuration for illustration — this listing is the upper group only.
We keep the PDW upper on the bench because Daniel Defense releases them in batches and we can usually grab a small allocation each run. If you're building a .300 BLK host for a short, light, suppressed carbine, this is the one that started the category. Add to cart and we'll get it moving.

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.
