What Makes This SBR Stand Out
This isn’t just another short-barreled rifle. The Daniel Defense PDW in 300 BLK was engineered specifically for the 7-inch barrel length. The 300 Blackout cartridge was designed to burn all its powder in barrels as short as 9 inches, but Daniel Defense optimized this system for even shorter lengths. The gas system is tuned to run both supersonic and subsonic ammunition reliably, something many other SBRs struggle with. The 1:7 twist rate stabilizes heavy subsonic rounds while still handling lighter supersonic loads. When you combine this with the closed bolt operation and Daniel Defense’s attention to detail, you get an SBR that works right out of the box without the tuning headaches common to other platforms.
California Ownership Considerations
For California residents, this SBR represents a practical choice for those who have gone through the NFA process. The 26-inch overall length makes it manageable in various settings, while the 300 BLK caliber offers excellent performance without excessive noise when paired with appropriate ammunition. At calgunsdepot, we understand California’s unique firearms landscape and can guide you through the transfer process. Remember that SBR ownership requires compliance with both federal NFA regulations and California state laws regarding configuration and transportation.

NFA-Regulated Firearm — ATF Form 4 Required
This is a short-barreled rifle (SBR) regulated under the National Firearms Act. Purchase requires an ATF Form 4 transfer, a $200 federal tax stamp, and approximately 30–120 days of ATF processing (eForm 4 is typically faster than paper). The firearm ships to a licensed FFL/SOT dealer of your choice; you take possession only after ATF approval.
SBRs are currently legal to own in most U.S. states. They remain prohibited or restricted for civilian possession in California, New York, New Jersey, Washington D.C., Hawaii, Iowa, Rhode Island, and Washington State. Check your state and local law before ordering. By placing an order you affirm that possession is lawful in your jurisdiction and that you are 21+ with no prohibiting factors under 18 U.S.C. §922(g).
