hELP!! My son has a center feed Accutrigger Savage Action that came with floor metal. We are trying to convert it to an adl style magazine to save the weight of the floor metal. We already have an H&S stock that is adl but the magazine that came with the rifle floats in the hole in the stock. My smith attached a tab to the back of the box that centers it on the rear action screw but it comes loose and floats up and interferes with the bolt. Does anyone know if someone makes a box that will just fit the opening in the bottom of the action so the spring can just hold it up and centered? Or what is the correct combination of parts? It is a short action for 308 style cartridges.
