Patent number: 9151553Abstract: 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.Type: GrantFiled: January 10, 2008Date of Patent: October 6, 2015Assignee: Smith & Wesson Corp.Inventors: Robert L.

Patent number: 7866077Abstract: A striker assembly for a firearm and a method of assembly the striker assembly is disclosed. The striker assembly includes a generally cylindrical body having a first distal end, a middle portion, and a second distal end. A coaxial spring encompasses the middle portion of the body and abuts an annular ring on the first distal end. The striker assembly also has a spacer having a first side and a second side with the first side of the spacer abutting a ridge on the second distal end of the body. A snap ring holds the spacer in place on the spacer's second side, and the snap ring is secured by a circumferential groove in the second distal end of the body. Finally, the striker assembly includes a cap that abuts the coaxial spring and encompasses the second distal end of the body, the spacer, and the snap ring.Type: GrantFiled: January 9, 2008Date of Patent: January 11, 2011Assignee: Smith & Wesson Corp.Inventors: Robert L.

Patent number: 6308448Abstract: An interlocked firing mechanism for a gun includes a trigger, a sear and a firing pin having a depending leg, wherein the firing pin is movable in a rectilinear manner along a firing axis. The depending leg of the firing pin is adapted to have a contact surface, while the sear is adapted to have a control surface in mating engagement with the contact surface at a time prior to firing of the gun. The contact surface and the control surface of the interlocked firing mechanism of the present invention are further adapted to have parallel surfaces which mate with one another along a mating axis, defining an edge of a mating plane, which is set at a predetermined angle from a line perpendicular to the firing axis.Type: GrantFiled: April 30, 1999Date of Patent: October 30, 2001Assignee: Smith & Wesson CorporationInventors: John Kapusta, John Pliska
