Daniel Defense DDM4 PDW SBR, .300 Blackout, No Magazine

Product Description

The Daniel Defense DDM4 PDW, part 02-088-22220-067, is an NFA short-barrelled rifle in 300 Blackout built on a 7-inch S2W profile barrel with a pistol-length gas system, and Daniel Defense supplies this part number without a magazine.

The only difference from the standard part number is that no magazine is packed with it. Daniel Defense builds the configuration for customers whose jurisdictions regulate capacity, where the local dealer fits a compliant magazine instead. Order the standard DDM4 PDW SBR configuration instead if you do not need it. Magazine rules are a local matter and they move, so satisfy yourself about the current requirements for your jurisdiction. Call 817-393-4000 for help sourcing a compliant magazine, or see our magazine selection.

Frequently Asked Questions

Q: What makes this the shortest Daniel Defense rifle configuration?

A: The 7-inch barrel and the Maxim Defense CQB Gen 7 stock together bring overall length down to 21 inches collapsed and 25 1/2 inches extended with the muzzle device. The MFR XL 6.0 M-LOK rail is sized to match, covering six inches of that barrel.

Q: Which magazine is this PDW configuration designed around?

A: The Magpul PMAG 30 AR 300 B GEN M3. This part number arrives without it, which is the entire point of the SKU: buyers in capacity-regulated jurisdictions source a magazine locally. Confirm your own rules first, then call 817-393-4000 for help selecting one.

Q: Does 300 Blackout make sense out of a 7-inch barrel?

A: That is what the cartridge was designed for. The 7-inch 300 Blackout Cold Hammer Forged barrel keeps subsonic loads subsonic and still produces useful ballistics from a very short tube, which is not something 5.56 manages well at the same barrel length.

Q: Is the no-magazine PDW still an NFA firearm?

A: Yes. The short barrel is what triggers NFA status, not the contents of the box, so a BATFE tax stamp and an approved transfer through a dealer holding a Special Occupational Tax stamp are required. Western Sport is an SOT. We state no wait times or tax amounts.

Q: What is the muzzle thread on the 300 Blackout PDW?

A: 5/8 x 24 TPI, with a Daniel Defense Linear Compensator fitted from the factory. The linear compensator pushes blast forward instead of sideways, which on a barrel this short makes a real difference to the shooter and to anyone standing nearby.

Q: Can Western Sport receive this transfer?

A: Yes. We are a licensed FFL and an SOT in Roanoke, Texas, and a short-barrelled rifle transfer requires both. As with every firearm we sell, it moves through a licensed FFL. Call 817-393-4000 and we will explain what the transfer involves on our end.
