Q Tall Boy
The Q Tall Boy is Q LLC’s 2026 7.62mm suppressor built for one purpose: maximum sound suppression, especially with subsonic .300 Blackout. Where many 7.62 suppressors balance size, weight, and sound reduction, the Tall Boy prioritizes sound reduction above all else — making it the right choice for dedicated subsonic hosts and precision rifle shooters who want the quietest possible report.

Why Maximum Suppression Matters on .300 Blackout Subsonic
Subsonic .300 Blackout is one of the quietest centerfire rifle cartridges available when suppressed, but achieving that potential requires a suppressor with sufficient baffle stack volume to capture the gas from a large, slow-moving 220-grain projectile. The Tall Boy’s design prioritizes baffle volume over compact dimensions, giving it an edge over shorter suppressors on subsonic hosts. For dedicated suppressed .300 BLK builds, dedicated hog hunting rigs, or precision .308 shooters who run subsonic loads, the Tall Boy delivers sound levels that shorter cans simply cannot match.
Q Tall Boy Specifications
Caliber: 7.62mm (.308 Win / .300 Blackout / 6.5 Creedmoor and compatible). Mount: Quickie fast-attach taper mount. Optimized for: subsonic .300 Blackout and standard .308 Win. The Tall Boy uses Q’s Quickie mounting system, compatible with all Q Quickie-pattern muzzle devices already installed on your host firearm.
Tall Boy vs Q Lefty: Choosing Your Q Suppressor
The Tall Boy and Q Lefty are complementary products covering different caliber ranges. The Lefty handles 5.56 NATO and 6mm ARC with Low Blow backpressure reduction; the Tall Boy handles 7.62mm with maximum sound suppression as the priority. If you run both an AR-15 and a .308 or .300 BLK host, both suppressors use Q’s Quickie mount — meaning one set of muzzle devices covers both cans.
