发明名称 Bolt action firearm and its method of assembly
摘要 Several improvements to the components and assembly method of a bolt-action firearm are disclosed. An improved bolt includes two separate members, which makes the bolt less expensive to manufacture while having a stronger extension handle. An improved takedown system and buttonless stop provide two easy ways to remove a bolt from a receiver when desired without misplacing any parts. An improved scope mount has a base connected to a receiver with two ends that substantially cover the top surface of the receiver and a middle portion that is narrowed over an opening to the receiver to accommodate a cartridge. A method of assembling a firearm involves providing a barrel with a threaded portion, fitting a crush washer over the threaded portion, inserting the threaded portion into a corresponding threaded portion of a receiver, and adjusting the barrel about the crush washer until a proper headspace is achieved.
