Q LLC BOOMBOX-86-12IN-PISTOL Boombox 8.6 Blackout 20+1 12" Bead Blasted Threaded Barrel, M-LOK Handguard, Aluminum Receiver w/Picatinny Rail, Black Pistol Brace, Black Polymer Grip

The Q Boombox 8.6 Blackout pistol is a short-stroke, direct-impingement semi-automatic built for shooters who want precision and modularity in a compact package. At just 5 lbs 8 oz with a 12-inch 416R stainless barrel, the Boombox delivers the punch of 8.6 Blackout in a form factor that handles like a rifle but sizes down to pistol convenience. The 20+1 magazine capacity and collapsible stock—ranging from 8.375 inches to 13 inches—give you flexibility whether you're running it as a standalone firearm or building around it for a specific mission.

This is a shooter's platform, not a compromise. The upper and lower receivers are precision-machined from 7075 aluminum, with a continuous M1913 Picatinny rail running the full length of the top for optics and accessories. The Q-Sert handguard spans 11 inches with integrated M-LOK attachment points, so mounting lights, slings, or rails is straightforward. The trigger is user-tuned to 3.25–3.75 lbs, and the safety lever is ambidextrous AR-15 pattern—familiar controls for anyone with modern rifle experience.

The Boombox ships ready to shoot but completely configurable. The threaded barrel (M18x1.5 with a tapered shoulder) comes fitted with Q's XL Cherry Bomb muzzle device and is set to a 1:3 twist for stable 8.6 Blackout ballistics. The Reptilia CQG-NB grip and two-position collapsible brace round out the ergonomics. You'll get one SR-25 pattern magazine; optics, suppressors, and additional magazines are separate choices based on your role.

Whether you're setting up a suppressed close-quarters build, a precision 8.6 Blackout pistol, or a modular testbed for ammo development, the Boombox is engineered for tinkerers and dedicated shooters who expect quality components and logical design.
