The Q Boom Box: Big Performance in a Compact Package
When Q announced they were bringing the 8.6 Blackout cartridge to the market, serious shooters took notice. Now they’ve packaged that impressive round into the Boom Box SBR, creating what might be the most capable short-barreled rifle available today. At just 31.25 inches overall with a 12-inch barrel, this isn’t just another compact rifle—it’s a purpose-built tool that delivers performance far beyond what you’d expect from its size.
What Makes the Boom Box Special
Most SBRs sacrifice ballistics for compactness, but the Boom Box changes that equation entirely. The 8.6 Blackout cartridge was specifically designed for short barrels, maintaining velocity and energy that other calibers lose when you cut barrel length. This means you’re getting terminal performance similar to much larger rifles in a package that handles like a PDW. The closed bolt semi-auto action provides reliable function whether you’re shooting suppressed or unsuppressed, and the M18x1.5 thread pitch gives you excellent suppressor mounting options. At 5 pounds 8 ounces, you can carry this rifle all day without fatigue, yet it has the heft to manage the 8.6 Blackout’s recoil effectively.
Florida Shooting Applications
Here in Florida, we have unique shooting environments that demand versatile firearms. Whether you’re dealing with thick brush in Central Florida, open spaces in the Panhandle, or the varied terrain throughout our state, the Boom Box adapts. The 8.6 Blackout cartridge performs exceptionally well on Florida’s abundant hog population, while remaining manageable for range use. The compact size makes it perfect for vehicle storage or navigating through Florida’s dense vegetation. At sunshinegunshop, we’ve seen Florida shooters appreciate firearms that can handle multiple roles, and the Boom Box delivers exactly that capability.

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 purchasing this SBR?
Purchasing an SBR requires filing a Form 4 with the ATF. We handle all the paperwork for you—you just need to provide fingerprints, passport photo, and complete the background check. Once approved, you can take possession through your chosen Florida FFL.
How long does the NFA approval typically take?
Current ATF processing times for Form 4s average 6-9 months for individual applications. Trust applications through an LLC or corporation often process faster, typically 3-6 months. We stay updated on current processing times to give you the most accurate estimate.
How do you ship NFA items to Florida FFLs?
We ship all NFA firearms directly to your chosen Florida FFL dealer once your Form 4 is approved. The firearm remains at their location until you receive your tax stamp. We coordinate everything between you, the ATF, and your FFL to make the process smooth.
What makes the 8.6 Blackout a good choice for an SBR?
The 8.6 Blackout was specifically designed for short barrels, maintaining excellent ballistics where other calibers lose performance. It delivers substantial energy on target while being manageable to shoot, making it ideal for hunting, defense, and general use in a compact package.

This Boom Box handles Florida hogs like nothing else. The 8.6 Blackout hits hard but the rifle stays manageable. Q’s quality shows in every detail—worth every penny for serious shooters.

Perfect size for vehicle storage and Florida terrain. Recoil is milder than I expected for the caliber. Only wish magazines were more readily available locally, but online ordering works fine.
Carlos M. (verified owner) –
Ran this suppressed at my local range and impressed everyone. The 12-inch barrel with 8.6 Blackout is a game changer. Heavy enough to be stable, light enough to carry all day in the Everglades.
