The Fletcher Rifle Works ST-174-HUB-LH Hub Mount CAT QD is a purpose-built suppressor adapter designed to mate modular cans using the common HUB 1.375"x24 rear thread to Fletcher CAT QD muzzle devices. Precision machined with left-hand threading, it replaces a fixed direct-thread rear cap and gives your suppressor a secure quick-detach interface while maintaining proper alignment.

This adapter threads into the rear of compatible suppressors and locks onto CAT QD muzzle devices, making it easy to move a single can between multiple hosts without tools. Ideal for shooters who regularly swap suppressors among rifles for range use, training, or general shooting, it emphasizes repeatable lockup and straightforward installation. Fletcher Rifle Works is known for thoughtful suppressor accessory design and careful machining that supports reliable performance.
