Abstract

A strong, durable, lightweight long gun stock comprising a rigid insert molded of reinforced thermoplastic material together with a foaming agent. The insert is over-molded with a thermoplastic material which provides the stock with the desired surface characteristics. The insert is dimensioned with respect to its over-molded surfaces to be smaller than the finished stock and is designed to give maximum strength to the stock. The insert is shaped to promote the flow of the over-mold material and to minimize shrinking, swelling or distortion of the insert. The over-mold material may be a hard, un-foamed material or a thermoplastic elastomer. The hard un-foamed over-mold material mechanically bonds with the insert and provides the stock with an extremely smooth, hard outer surface. The thermoplastic elastomer over-mold material is compatible with the material of the insert and bonds both mechanically and chemically with the insert, providing the stock with a soft, quiet, non-slip surface.
