The Q LLC Fix SBR in 8.6 Blackout is a short-barrel rifle purpose-built for shooters who want a compact, maneuverable platform without sacrificing firepower or precision. This 12-inch tapered-threaded barrel rifle chambered in 8.6 Blackout delivers serious performance in a package that handles like a modern carbine—ideal for shooters looking for a specialized short-barrel rifle that balances agility with hard-hitting ballistics.
Built around a one-piece receiver design, the Fix SBR keeps weight to a minimum at just 5.4 lbs, making it genuinely packable without feeling like a toy. The lightweight stainless steel barrel features a 1:3 twist rate optimized for 8.6 Blackout ballistics, and the tapered profile reduces unnecessary mass while maintaining rigidity. Muzzle threading is M18-1.5 (the standard for 8.6 Blackout), ready to accept suppressors or brakes—the included Cherry Bomb muzzle brake gets you on target immediately, though a suppressor would be a natural pairing for this cartridge's subsonic potential.
Ergonomics and modularity matter on a modern rifle, and the Fix delivers both. The fully adjustable folding stock adapts to different shooting positions and gear configurations, while the short M1913 Picatinny rail provides a clean mounting surface for optics without excess weight or profile. The free-float Q-Sert handguard keeps the barrel unimpeded for accuracy, and the 2-stage match trigger and AR-style controls are familiar to anyone comfortable with the modern sporting rifle platform. Magazine compatibility with SR-25 mags opens up a deep supply chain.
A word on ammunition: 8.6 Blackout cartridges loaded for semi-auto rifles can sometimes produce light primer strikes in this design due to hard primers used in some match loads. Standard hunting and defensive 8.6 Blackout ammunition should function reliably, but reloaders and match shooters should verify primer hardness if experiencing issues. Optics and suppressors are sold separately.

The 8.6 Blackout is a 8.6mm cartridge designed for modern rifles. It offers effective performance in a compact platform and is known for subsonic bullet availability and compatibility with AR-pattern magazines and controls—making it a specialized choice for shooters seeking something beyond the typical .300 Blackout.
Yes. The barrel features M18-1.5 muzzle threading standard for 8.6 Blackout, which accepts suppressors with that bore. The included Cherry Bomb brake can be removed to mount a suppressor. Optics and suppressors are not included.
The Fix is designed for 8.6 Blackout, but ammunition loaded with hard primers (commonly found in match and semi-auto-specific loads) may occasionally produce light primer strikes.
