Q Mini Fix SBR .300 BLK 10rd Magazine 8" 5/8x24 Threaded Barrel Black with Folding Stock NFA

The Q Mini Fix SBR in .300 BLK is a compact, precision-built short-barreled rifle purpose-made for shooters who need serious capability in a hand-friendly package. With an 8-inch barrel threaded 5/8x24 for suppressor mounting, a folding stock for stowage and maneuverability, and the ability to run a 10-round magazine, this is a rifle that punches well beyond its footprint. Whether you're working from a truck, a blind, or navigating tight terrain, the Mini Fix delivers the balance of accuracy and speed that separates real working rifles from the rest.

Q designed the Mini Fix around uncompromising performance in a compact frame. The 8-inch .300 BLK barrel is optimized to maintain velocity and energy while staying short enough to feel like an extension of your body rather than a burden. The suppressor-ready 5/8x24 threads let you run Q's Quickie Fast-Attach silencers—or any compatible suppressor—to tame report and recoil. The folding stock isn't window dressing; it's genuine utility for carry, storage, and rapid deployment. Pair that with a 2-stage trigger tuned for precision and you've got an SBR that handles like a carbine but shoots like it's got a full-length barrel.

Build quality is clean and purposeful. The Mini Fix is finished tough, assembled to exacting tolerances, and ready to earn its keep in the field. Modular design means you can adapt it to your setup—whether that's optics, lights, stocks, or grips—without fussing with proprietary systems. This is a rifle for people who know that smaller doesn't mean compromise.

Note: As an NFA-registered SBR, this rifle requires a valid Form 1 or Form 4 stamp and compliance with all federal and local regulations. Ensure you understand your state and local laws before purchase.

Frequently Asked Questions

Is the Q Mini Fix compatible with suppressors?

Yes. The barrel is threaded 5/8x24, the standard for .300 BLK suppressors. Q makes the Quickie Fast-Attach line designed specifically for their platform, but any suppressor with a 5/8x24 mounting interface will work.

What makes the folding stock useful?

The folding stock reduces overall length dramatically, making the rifle easier to stow in vehicles, drag bags, or tight spaces where a standard buttstock would catch or bind. It folds and unfolds quickly, so you don't sacrifice functionality for portability—just flip it out when you're ready to shoot.

What caliber and magazine capacity does this SBR use?

The Mini Fix is chambered in .300 BLK and feeds 10-round magazines. This caliber was designed for short barrels and suppressors, so you're getting excellent ballistic performance from the 8-inch barrel even when suppressed.

Do I need an NFA stamp to own this rifle?

Yes. As a short-barreled rifle (SBR), the Mini Fix requires a valid federal NFA stamp. You'll need to file a Form 1 (if building) or Form 4 (if transferring a registered SBR) with the ATF, pay the $200 tax, and comply with all state and local laws. Ensure you understand your local regulations before purchasing.

Is the trigger adjustable?

The rifle comes with a 2-stage trigger tuned for precision shooting. We don't have details on user adjustability—reach out to our team if you have specific tuning questions.
