The Yankee Hill Machine QD Mount Thread Protector is a QD mount thread protector from Yankee Hill Machine. Yankee Hill Machine machines it (Yankee Hill Machine part no. YHM-3114) to factory tolerances rather than as a generic aftermarket stand-in. It threads onto an exposed muzzle to protect the barrel’s external threads from dings, dirt, and corrosion whenever a suppressor or muzzle device is not mounted. A bare threaded muzzle is an easy way to buff a thread crest or let grit into the threads, and a low-profile protector keeps that interface ready for the next time a can goes on. It is a practical pickup for a home-built suppressor host or a duty rifle that needs this exact piece of hardware on hand.

Key Specifications

• Low-profile cap design threads on flush so it does not add meaningful length or snag on a holster or case.
• Genuine Yankee Hill Machine part is sourced from Yankee Hill Machine through an authorized distributor rather than an unbranded aftermarket copy.
