The Q Mini Fix 300 Blackout is a short-barreled pistol built on a robust one-piece receiver and designed for shooters who want serious capability in a compact package. With an 8-inch barrel and the ability to run standard AR magazines, this pistol delivers the subsonic power of .300 Blackout in a handling-friendly form factor that works equally well for home defense, truck gun duty, or suppressed shooting. The tapered, threaded barrel threads at 5/8-24, so you can add a suppressor or other muzzle devices to suit your mission.
The Mini Fix strips away complexity while keeping what matters. Its free-floating Q-Sert handguard stays true regardless of how tight you grip it, a 45-degree short-throw bolt handle gets you back into action fast, and a proper 2-stage match trigger gives you predictable breaks. The one-piece receiver is cut with a full-length M1913 Picatinny rail on top, so mounting optics or a red dot is straightforward. Controls follow AR pattern—familiar to anyone who's run a modern rifle or carbine—and the black SBA3 brace and black polymer grips round out a clean, no-frills setup.
At just under 4 pounds and 17 inches overall, the Mini Fix 300 Blackout stays light and pointable without sacrificing the ballistics that make .300 Blackout worth shooting. Whether you're building a dedicated short-range thumper, a can-ready truck gun, or your first AR-pattern pistol, this one delivers genuine Q engineering without the marketing noise.

Yes. The 8-inch barrel is threaded 5/8-24, which is the standard thread pitch for .300 Blackout suppressors and muzzle devices. The tapered profile ensures a clean, concentric fit.
The Q-Sert handguard is free-floating, meaning it doesn't contact the barrel. Free-floating handguards eliminate pressure points that can shift zero, so accuracy remains consistent whether you're gripping lightly or firmly.
The barrel has a 1:5 twist, which is optimized for a wide range of .300 Blackout projectiles, including subsonic rounds.
