Description
The Ultimate Quiet Hunter
When Q announced the Minifix SD, we knew it would be something special. This isn’t just another short-barreled rifle—it’s a purpose-built system designed from the ground up for suppressed shooting. The integrated suppressor isn’t an afterthought; it’s part of the weapon’s DNA. At just 33.75 inches overall with the can attached, this package handles like a dream in tight spaces while delivering the kind of quiet performance that makes other bolt guns seem loud by comparison.
What Makes This SBR Special
Most SBRs on the market are built on AR platforms, but the Minifix SD takes a different approach. The bolt-action design eliminates gas blowback entirely, making it cleaner and more pleasant to shoot suppressed than any gas-operated system. The 8-inch barrel with its aggressive 1:5 twist rate stabilizes heavy subsonic 300BLK rounds perfectly, ensuring reliable expansion and terminal performance even at reduced velocities. This isn’t a chopped-down rifle—it’s engineered specifically for this configuration, with every component optimized for suppressed use. The result is a weapon that feels balanced, shoots smoothly, and maintains accuracy shot after shot without the fouling issues common in suppressed AR platforms.
Built for Arizona
Here in southern Arizona, we understand the value of a compact, quiet rifle. Whether you’re hunting javelina in the brush, dealing with predators on your property, or just want a discreet home defense option that won’t deafen you indoors, the Minifix SD makes sense. The 300BLK chambering gives you plenty of power for medium game, while the suppressed bolt-action design means you can take follow-up shots without losing your night vision or disturbing the neighbors. At Tucson Arms, we’ve seen growing interest in these specialized tools from practical shooters who value effectiveness over flash.

Remember that all NFA items require proper paperwork and approval before transfer. We guide you through every step of the process, from selecting the right trust to submitting your Form 4. Once approved, we ship directly to your chosen Arizona FFL for pickup.
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?
You'll need to submit a Form 4 through the ATF, which requires fingerprints, passport photos, and either an individual application or gun trust. We handle the paperwork submission for you and keep you updated throughout the process. Most customers find it straightforward with our guidance.
How long does approval take?
Current ATF processing times for Form 4s average 6-9 months for electronic submissions. We submit everything electronically to speed up the process. The wait varies but we've seen approvals come through in as little as four months recently.
Do you ship to Arizona FFLs?
Yes, we ship all NFA items directly to your chosen Arizona FFL once your Form 4 is approved. We work with dealers across the state and can recommend one near you if needed. Your FFL will handle the final transfer when you pick up the firearm.
Why 300BLK for this SBR?
300BLK is ideal for short barrels because it burns all its powder in about 9 inches of barrel. In this 8-inch configuration with subsonic ammo, you get reliable expansion and terminal performance without excessive noise. It's perfect for hunting medium game or home defense where overpenetration is a concern.

Took this out for javelina last season. The quietest rifle I’ve ever shot. Bolt action means no gas to the face when suppressed. Worth every penny and the wait.

Impressive engineering. The balance is perfect, and it shoots subsonics like a dream. Only wish it came with more than one magazine. Customer service at Tucson Arms made the NFA process painless.

This replaced my AR for nighttime predator control. No more waking up the neighbors. The integrated suppressor design really works—no poi shift between supersonic and subsonic loads. Solid Arizona tool.
