A QD mount screws into the back of a modular suppressor and lets it lock onto a matching muzzle device. The muzzle device stays on the rifle; the suppressor and mount come off together. You need both halves: this mount and a muzzle device that presents the same interface.
This one locks onto any Stealth LoK muzzle device and threads into suppressors with a HUB 1.375x24 rear.

Which ones fit your barrel and host?
See all 597 in the Builder- The Stealth LoK QD System is a patent pending quick detach system used with Engaged Industries QD suppressors, and was designed to be an upgrade attachment system for any suppressor brand using 1.375-24 threads, sometimes referred to as HUB thread.
- The Stealth Lok QD system lets the suppressor be installed rapidly on multiple firearms. Six locking lugs and the ability to install the suppressor in any orientation make it quick and easy to attach in any light condition, and without a ratcheting mechanism it is very stealthy when connecting and disconnecting. There is no secondary mechanism to operate to attach the suppressor; the secondary lock is built into the system, which makes it an ideal one handed attachment system for platforms whose handguard extends beyond the barrel.
- Adds 0.29" of length to the suppressor; total length including internal threads is 0.64". Muzzle device protrusion inside the suppressor runs 0.0 to 1.5" depending on the muzzle device.
- Finish: black nitrided alloy steel, Rc 52+.
- Compatible with any suppressor using 1.375-24 threads. Verify the threads of your suppressor on the manufacturer website or contact their customer support.
