The Yankee Hill Machine VICTRA-12 Jam Nut is a VICTRA-12 mount jam nut from Yankee Hill Machine. Yankee Hill Machine machines it (Yankee Hill Machine part no. YHM-1250) to factory tolerances rather than as a generic aftermarket stand-in. It is a jam nut that locks a mount or thread adapter in place on the barrel once it has been properly indexed. Torquing this down after clocking the mount keeps the whole assembly from working itself loose under sustained recoil. It is a practical pickup for anyone running a suppressor setup where the small parts matter as much as the can itself.

Key Specifications

• Mount lock-down hardware torques down against the mount or adapter once it is indexed, to keep it from backing off the barrel.
• Genuine Yankee Hill Machine part is sourced from Yankee Hill Machine through an authorized distributor rather than an unbranded aftermarket copy.
