Description
Built for Performance, Ready for Arizona
When you’re looking for a short-barreled rifle that delivers without compromise, the Breacher’s Custom Guns Daniel Defense SD stands out. This isn’t just another 9mm carbine—it’s a purpose-built SBR that combines Daniel Defense’s legendary reliability with Breacher’s Custom Guns’ precision craftsmanship. At 6 pounds 9 ounces with a 5.75-inch barrel, this rifle moves like an extension of your body while delivering the terminal performance you need.
What Makes This SBR Different
Most 9mm SBRs on the market are either converted pistols or budget-range toys. The Breacher’s Custom Guns Daniel Defense SD is neither. This rifle starts with Daniel Defense’s closed-bolt semi-auto system—the same proven platform trusted by professionals worldwide. Breacher’s Custom Guns then takes that foundation and optimizes it for SBR use. They’ve tuned the gas system specifically for the 5.75-inch barrel length, ensuring reliable cycling with everything from 115-grain range ammo to 147-grain defensive loads. The result is a 9mm SBR that doesn’t just work—it excels. The closed-bolt operation means cleaner shooting and more consistent lockup than blowback systems, while the Daniel Defense heritage guarantees durability that stands up to serious use.

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).

Frequently Asked Questions
What's the NFA process for buying this SBR?
As an NFA item, this SBR requires a Form 4 transfer. We handle all the paperwork—you'll need to provide fingerprints, passport photos, and get your local chief law enforcement officer sign-off or use a gun trust. Once approved, we ship to your chosen FFL.
How long does the NFA approval take?
Current ATF processing times for Form 4 transfers average 6-9 months for individual applications, though trusts can sometimes process faster. We submit everything electronically to speed up the process, but the wait depends on ATF workload.
Do you ship to FFLs in Arizona?
Yes, we ship to any licensed FFL in Arizona. We recommend using an FFL familiar with NFA transfers. If you're in the Tucson area, you can pick up directly from our shop once your Form 4 is approved.
