Yankee Hill Machine sRx Thread Protector Black 4140 Steel

The Yankee Hill Machine sRx Thread Protector is a factory thread cover designed specifically for the YHM sRx suppressor mounting system. It installs onto the sRx muzzle device hub to shield the threads from impact damage, debris, and corrosion when the suppressor mount is not in use.

Machined from 4140 Chrome Moly Steel and finished in Black Oxide for lasting corrosion resistance, this compact protector measures just 0.5625" long with a 1" diameter and weighs only 0.448 oz. It is purpose-built for use with YHM sRx muzzle devices and is not compatible with the Phantom Q.D. mount system.

Manufactured in the USA by Yankee Hill Machine to factory tolerances for a precise, secure fit on the sRx hub.
