Yankee Hill Machine Universal Rifle Suppressor Mount Features The Yankee Hill Machine Universal Rifle Suppressor Mount is machined from 17-4PH heat treated steel with a Melonite QPQ finish delivering a durable and corrosion-resistant 1.696 oz mount adapter that converts compatible suppressors to a 5/8x24 direct thread barrel interface. Installation requires only a 3/4-inch open end wrench to remove the existing mount mechanism from the suppressor and thread on the Universal Rifle Suppressor Mount after which the now two-piece suppressor assembly threads directly onto the host barrel. The simplified direct thread design eliminates the risk of incorrect installation and suppressor loosening during use while maintaining straightforward removal when needed. The 1-3/8x24 mount thread pitch interfaces with the suppressor body while the 5/8x24 external thread mates directly with compatible rifle barrel muzzle threads for a secure and repeatable direct thread installation. The Melonite QPQ finish provides surface hardness and corrosion resistance appropriate for a muzzle-mounted component subject to sustained heat and pressure cycling. The universal design allows the mount to convert suppressors from a broad range of manufacturers that use the 1-3/8x24 internal mount thread pitch.
