Abstract
Tactical firearm systems and methods of manufacturing tactical firearm systems are discussed herein. In some embodiments, a tactical weapons platform can comprise a forend assembly adapted to house a portion of a barrel; a receiver assembly detachably coupled to the forend assembly and adapted to interface with a bolt action; and a butt stock assembly detachably coupled to the receiver assembly. In other embodiments, a modular stock assembly for a bolt action rifle can generally comprise a forend assembly, a receiver assembly, and a butt stock assembly. The forend assembly can have a body adapted to house a barrel in a free floating configuration, wherein the body surrounds at least a portion of the length of the barrel. The receiver assembly can be detachably coupled to the forend assembly and adapted to directly interface with a bolt action without bedding. The butt stock assembly can be detachably coupled the receiver assembly by a hinge. Other aspects, features, and embodiments are also claimed and described herein.
