The Yankee Hill Machine QD Mount Thread Protector caps the muzzle threads on a barrel when a suppressor or muzzle device is not installed, keeping the threads clean and protected from dings, dirt and moisture. The quick-detach style mounting design is intended for use with compatible QD suppressor mounting systems, making it simple to swap between a protector and a can in the field. Yankee Hill Machine is a well-known American maker of suppressor mounts, muzzle devices and AR-pattern components, and this is a practical, inexpensive piece of insurance for any threaded barrel that sees regular range or hunting use.
