Q Boombox Details

The Q Boombox is what you get when Q starts with the Honey Badger DNA, scales it up to a heavier hitter, and chambers it in a cartridge purpose-built for short barrels and suppressors. It's a 12-inch 8.6 Blackout SBR designed to run subsonic loads silly-quiet and supersonic loads with authority. Same rifle, same magazine, totally different terminal performance depending on what you load. 

The 12-inch 416R stainless barrel uses a 1:3 twist rate dialed in for 8.6 Blackout's heavy projectiles, where most other twist rates fall apart on subsonic stabilization. The XL Cherry Bomb muzzle device sits behind M18x1.5 threads, ready for Q suppressors like the Porq Chop or Short Chop. Whether you're running heavy subsonics for hog hunts or around the farm or supersonics for deer at moderate range, this rifle covers more ground than just about any SBR in the same footprint.

About the 8.6 Blackout Cartridge

Q designed 8.6 Blackout to do everything 300 Blackout couldn't. Heavier projectiles, more terminal energy, longer effective range, and subsonic loads that actually stay stable through the barrel. On a 12-inch host like the Boombox, the cartridge punches above its weight, the kind of energy you'd expect from a much longer rifle, in a package that fits in a normal range bag. Pair it with a Q can and you've got one of the most versatile suppressed setups on the market.
