Q, LLC BOOMBOX 8.6 BLK 20rd Short Barrel Rifle, 12” 1:3" Threaded Barrel 

Overview

Designed and built by the team behind the Honey Badger, the Q, LLC BoomBox is a purpose-built short-barreled rifle (SBR) chambered in the heavy-hitting 8.6 BLK. Optimized from barrel to bolt for extreme terminal performance and precision, the BoomBox pairs multi-caliber flexibility with real-world accuracy—capable of 1 MOA at 300 yards when paired with the recommended heavy subsonic projectiles and proper suppression. Lightweight and compact, it delivers big-game energy while remaining remarkably quiet with subsonic loads.

• Literally The Best Trigger Ever Made: Two-stage match trigger with a crisp break and lightning fast reset (3.25–3.75 lb pull).
• Modular, multi-caliber capable: Quick barrel swaps in minutes—no bench or vice required.
