Q Boombox

Q Boombox

The Q Boombox is Q's semi-automatic 8.6 BLK rifle — an AR-pattern direct impingement gas gun built specifically for the 8.6 BLK cartridge. While The Fix provides a bolt-action platform for 8.6 BLK precision shooting, the Boombox is the semi-auto companion for higher-volume 8.6 BLK use. Pairs directly with the Porq Chop and Short Chop suppressors via the Cherry Bomb XL M18×1.5 muzzle device. The 8.6 BLK cartridge is Q's proprietary round derived from 6.5 Creedmoor — subsonic loads run heavy .338-diameter bullets (285–350 gr), delivering substantially more energy on target than .300 BLK subsonics. Requires a 12" barrel minimum for Q's gas gun implementation.
