Key Specifications

Performance & Engineering

The Southpaw represents Q’s commitment to 5.56 suppression without compromise. Its stainless steel construction provides superior corrosion resistance, critical for shooters who operate in harsh environments or with unsuppressed follow-up shots. The ~6″ profile keeps your rifle balanced and maneuverable, while the 9 oz weight barely impacts your setup. The QuickD mount system ensures zero POI shift between host transfers, allowing you to move the Southpaw between multiple AR platforms without loss of zero.

At approximately 30 dB of sound reduction, the Southpaw brings rifle reports down to hearing-safe levels for most shooters, protecting your hearing during extended shooting sessions. Q’s engineering excellence means tight tolerances, consistent performance, and durability that stands up to sustained fire. This is not a compromise design—it’s a purpose-built suppressor for the modern AR operator.
