Q Boombox 8.6 Blackout 12″ Barrel SBR BOOMBOX-86-12IN-SBR

Q Boombox 8.6 Blackout – 12" Barrel, 20+1 Capacity, XL Cherry Bomb Muzzle Device

Compact, powerful, and purpose-built, the Q Boombox delivers next-level performance in a semi-automatic 8.6 Blackout platform. Featuring a precision 12-inch 416R stainless steel fluted barrel with an ultra-fast 1:3 twist rate, the Boombox is engineered for superior stability, incredible energy transfer, and consistent accuracy—all in a package that's agile enough for real-world tactical applications.

This short-barreled rifle (NFA item) is built around a direct impingement gas system for smooth cycling, and comes outfitted with a 2-position adjustable stock, a lightweight 11-inch Q-Sert handguard, and the ergonomic Reptilia CQG-NB grip for maximum control and comfort. The included XL Cherry Bomb muzzle device helps tame recoil and improve shot-to-shot performance.

Finished with a durable hardcoat anodized finish (where shade variations are a normal part of the process), the Boombox looks as tough as it runs. Whether you’re building a compact suppressed setup or pushing the limits of what 8.6 Blackout can do, the Q Boombox is designed to deliver.
