The Q Boombox SBR 8.6BLK 8" 20RD Gray is Q’s compact AR-10 style short-barreled rifle, engineered to deliver AR-10 performance in an AR-15 sized package. Built to be exceptionally light yet brutally reliable, it is chambered in 8.6 BLK and designed to run both subsonic and supersonic ammunition without forcing you to carry multiple rifles.

This model features a 12" barrel with a fast 1:3 twist for stabilizing heavy projectiles, a direct impingement gas system, and an AR-15 style ambidextrous safety for intuitive control. The 11" Q-Sert handguard offers ample mounting space, while the adjustable stock and XL Cherry Bomb tapered muzzle device help fine-tune handling and recoil characteristics. Finished in clear anodized gray, the Boombox SBR is well suited for range use, hunting, and training where compact size and versatile ballistics are valued, reflecting Q’s reputation for innovative, purpose-built rifle designs.
