First claim
Opening claim text (preview).
That which is claimed is: 1 . A receiver blank comprising: a receiver body comprising a magazine well; and an insert, wherein: the insert must be removed from the receiver body to convert the receiver blank to a firearm receiver; and the insert comprises a water-soluble material. 2 . The receiver blank of claim 1 , wherein the insert comprises at least one protrusion extending away from the receiver body such that the at least one protrusion is visible. 3 . The receiver blank of claim 2 , wherein the entirety of the insert other than a portion of the at least one protrusion is not visible because the insert is internal to the receiver body. 4 . The receiver blank of claim 1 , wherein the insert is located internal to the receiver body and the insert is manufactured separately from the receiver body. 5 . The receiver blank of claim 1 , wherein the insert comprises a plurality of holes extending at least partially through the insert. 6 . The receiver blank of claim 1 , wherein the material of the receiver body and the insert comprises at least one selected from the group of plastic, thermoplastic, nylon, polyetherimide, polyoxymethylene, polytetrafluoroethylene, polyethylene, polypropylene, polyvinyl chloride, polystyrene, or carbon composite. 7 . The receiver blank of claim 1 , wherein the receiver body comprises at least one material selected from the group of plastic, thermoplastic, nylon, polyetherimide, polyoxymethylene, polytetrafluoroethylene, polyethylene, polypropylene, polyvinyl chloride, polystyrene, or carbon composite. 8 . The receiver blank of claim 1 , wherein the shape of the insert approximately corresponds to a fire-control cavity of the firearm receiver. 9 . The receiver blank of claim 8 , wherein the insert comprises at least one dimension that is smaller than a corresponding dimension of the fire-control cavity. 10 . The receiver blank of claim 1 , wherein the receiver body is a receiver for a handgun. 11 . The receiver blank of claim 1 , further comprising a portion for serialization. 12 . A receiver blank comprising: a receiver body; and an insert, wherein: the insert is located at least partially internal to the receiver body; the insert must be removed from the receiver body to convert the receiver blank to a firearm receiver; and the insert comprises a plurality of holes extending at least partially through the insert. 13 . The receiver blank of claim 12 , wherein the receiver body and the insert comprise the same material. 14 . The receiver blank of claim 12 , wherein: the receiver body comprises at least one material selected from the group of plastic, thermoplastic, nylon, polyetherimide, polyoxymethylene, polytetrafluoroethylene, polyethylene, polypropylene, polyvinyl chloride, polystyrene, or carbon composite; and the insert comprises a water-soluble material. 15 . The receiver blank of claim 12 , wherein the insert comprises at least one material selected from the group of a polyvinyl alcohol thermoplastic, a polyvinyl acetal, or a water-soluble synthetic polymer. 16 . The receiver blank of claim 12 , wherein the insert is manufactured separately from the receiver body. 17 . The receiver blank of claim 12 , wherein the shape of the insert approximately corresponds to a fire-control cavity of the firearm receiver. 18 . The receiver blank of claim 17 , wherein the insert comprises at least one dimension that is smaller than a corresponding dimension of the fire-control cavity. 19 . The receiver blank of claim 12 , wherein the receiver body is a receiver for a handgun. 20 . The receiver blank of claim 12 , further comprising a portion for serialization.
