摘要： A modular barrel assembly for firearms that includes a breech section formed from a high-strength material and a barrel section. the barrel section generally is formed separately from the breech section and can be formed from a different, lighter-weight material. Once formed, the barrel and breech sections are attached together to form the complete barrel assembly.

摘要： A firearm bolt prepared from an alloy of tungsten, nickel and iron having a density of about from 14.1 g/cc to 18.0 g/cc. The alloy preferably also contains at least one of molybdenum, cobalt, rhenium, tantalum and gold. The alloy is preferably manufactured by standard powder metallurgical techniques followed by a liquid phase sinter and vacuum anneal. The bolt can also be manufactured using solid state sintering. The bolt can also be manufactured by mechanically working the material after sintering, after annealing, or after both sintering and annealing.
