So I am wanting a Manners stock with mini chassis. What I am confused about is the bottom metal. I spoke to Manners today and was told that bottom metal is not included and would have to be sourced. What I am confused about is on Manners site, they list the mini chassis with bottom metal (screenshot below). If a stock equipped with a mini chassis comes with the chassis but no bottom metal, how do I go about buying the pictured Manners bottom metal?
