Q LLC Erect9r 9mm 1/2"x28 Direct Mount 17-4 Stainless Steel

The Q LLC Erect9r is a precision-machined direct-mount suppressor attachment purpose-built for 9mm pistol hosts. Cut from 17-4 stainless steel and finished with a heat-treated surface, this mount delivers the strength, wear resistance, and dimensional stability needed for repeated suppressor use in demanding range and duty environments.

Featuring a 1/2"x28 thread pattern, the Erect9r threads directly onto any compatible pistol barrel and provides a secure, rock-solid mounting interface for 9mm suppressors and muzzle accessories. The compact direct-mount geometry keeps your suppressor tucked tight to the muzzle, reducing overall length, improving balance, and eliminating the added weight and snag potential of a separate booster or piston system.

Part of the Q Erector Series, the Erect9r is engineered to Q LLC's exacting tolerances for a precise, repeatable fit shot after shot. Whether you are running a dedicated suppressor host, swapping mounts between builds, or simplifying your fixed-barrel setup, this purpose-built component is designed to anchor your 9mm suppressor system with confidence.
