Yankee Hill 4400 sRx QD Adapter 9mm Luger 1.375x24 HUB 17-4 Stainless Steel

The Yankee Hill 4400 sRx QD Adapter is a low-profile quick-detach mounting interface that attaches a HUB-compatible suppressor to a 9mm Luger barrel using the industry-standard HUB (1.375"x24) thread pattern. Machined from 17-4 PH stainless steel and finished in black oxide, this adapter is built for durability and corrosion resistance in hard-use environments.

The sRx adapter is rated for 9mm (.390" diameter) or smaller calibers and adds only 0.60" of length to your suppressor setup. An internal taper seal in front of the threads locks the suppressor in place using friction, eliminating the need to shim or time the mount to the barrel. The design features no moving parts, with a large taper providing consistent, repeatable mounting on every install.

At just 1.88 oz, the 4400 keeps your 9mm Luger host lightweight and uncluttered while delivering a secure, repeatable suppressor interface. Backed by Yankee Hill Machine's reputation as an American manufacturer of suppressor accessories, the sRx QD Adapter is a versatile mounting solution for any HUB-threaded suppressor.
