Boom Box by Q

Q BOOM BOX 8.6 BLACKOUT SBR - HONEY BADGER DNA, NEXT-GENERATION CALIBER

The Q Boom Box is what happens when you take the Honey Badger's DNA and feed it 8.6 Blackout. This compact short-barreled rifle is purpose-built for serious suppressed shooting, delivering devastating energy on target from a rifle that weighs just 5.5 pounds. Q built the Boom Box around the 8.6 Blackout cartridge, which outperforms 300 Blackout in terminal energy, effective distance, and subsonic capability. The 12-inch bead-blasted stainless steel barrel with a 1:3 twist rate is optimized specifically for 8.6 BLK projectiles, delivering consistent accuracy and stability with both subsonic and supersonic loads. Whether you're running heavy subsonic loads for hearing-safe performance or switching to supersonic for extended reach, the Boom Box handles both without compromise. It ships ready for your Q suppressor, with an M18x1.5 threaded muzzle topped by Q's own XL Cherry Bomb muzzle device.

CAPITOL ARMORY'S OPINION

The Boom Box is a purpose-built suppressor host in a way most SBRs aren't. The 8.6 Blackout cartridge was designed for suppressed use, and Q engineered this rifle specifically around it, so you're not working around compromises baked in by a different caliber's design decisions. The adjustable gas block gives you real tuning flexibility when running cans, and Q's trigger lives up to the name. At 5.5 pounds, this is a seriously capable large-frame SBR that carries like a compact. If you're already running Q suppressors or planning to, the Boom Box is the natural platform to build around. This is a factory SBR requiring NFA approval before it ships, and we handle that entire process for you.
