The Q Boombox 8.6 Blackout pistol (brand part no. BOOMBOX8612INPISTOL) chambers the hard-hitting 8.6 Blackout cartridge in a 12-inch 416R stainless steel barrel with a bead-blasted finish, built for shooters who want big-bore power in a genuinely braced AR pistol. Q LLC cuts a fast 1-in-3 twist to stabilize heavy 8.6 Blackout bullets and threads the muzzle in M18x1.5 for the included XL Cherry Bomb muzzle device. An 11-inch Q-Sert M-LOK handguard, a Reptilia CQG-NB grip, and Q’s own AR-15 style ambidextrous safety round out the ergonomics, all riding on a 7075 aluminum receiver with a continuous M1913 top rail. Among the pistol-caliber carbines in our AR pistols lineup, the Boombox stands out for its fast-twist barrel built specifically for 8.6 Blackout.
