(57) Firearms and firearm components (16,16',20,30A,30B,30C,50A,50B) are constructed from
bonded multi-metallic base materials comprising at least two dissimilar metallic materials
(12',14') having different properties, such as weight, density, wear resistance, durability,
hardness, and the like, bonded to one another. The components (16,16',20,30A,30B,30C,50A,50B)
are fabricated such that the metallic material having higher impact- and wear-resistance
(12') is positioned at areas that experience impact, or that include bearing points,
wear points, and interfaces with other components, while a lighter weight metallic
material (14') is positioned at component locations that don't have rigorous material
property requirements. The bonded multi-metallic materials (12',14') may be explosively
bonded multi-metallic materials.
