The Yankee Hill Machine Picatinny Vise Jaws (YHM part no. YHM7350) are professional-quality steel jaws that drop into any standard bench vise to provide a solid clamping surface on any Picatinny rail. YHM builds them to guarantee correct alignment between an upper receiver and a YHM free-float handguard during installation, a step where an improvised clamp can twist the rail out of true. Because the jaws slip into a vise rather than requiring a dedicated fixture, they work with equipment most home and shop benches already have. Per the manufacturer, this item is not shipped directly to California.
