Abstract
A cam race comprising a hardened material (harder than a material of an upper receiver) is provided to increase durability of a firearm. The cam race is fit within a groove within an interior sidewall of an upper receiver of the firearm. The cam race comprises a body that is fit within the groove, and a plurality of fastener pins extending away from a rear face of the body that fit within corresponding through-holes of the upper receiver. Distal ends of each of the fastener pins are deformed to form a riveted connection between the cam race and the upper receiver. The cam race defines a slide face along which a cam pin of the firearm slides during a firing process, thereby increasing the durability of the firearm against undesired formation of defects within the interior sidewall of the upper receiver.
Claims16
A cam race for an upper receiver of a firearm, the cam race comprising:
- a body defining a slide face and an opposite rear face;
- and
- a plurality of fastener pins extending away from the opposite rear face, wherein the plurality of fastener pins are integrally formed with the body;
- wherein the body is positioned within a groove of the upper receiver, wherein the plurality of fastener pins are received through through-holes extending from the groove to an exterior sidewall of the upper receiver, and wherein the exterior sidewall defines a raised rail aligned with the groove, and
- wherein the body and the plurality of fastener pins comprise a material selected from:
- steel or titanium and wherein the body and the plurality of fastener pins are nitride finished.
An upper receiver assembly for a firearm, the upper receiver assembly comprising:
- an upper receiver defining a groove within an interior sidewall, wherein the groove defines a plurality of through-holes extending through the interior sidewall of the upper receiver to an exterior sidewall of the upper receiver, wherein the exterior sidewall defines a raised rail aligned with the groove;
- and
- a cam race comprising:
- a body defining a slide face and an opposite rear face, wherein the body is positioned within the groove;
- and
- a plurality of fastener pins extending away from the opposite rear face, wherein each of the plurality of fastener pins extend through a corresponding through-hole.
A method of manufacturing an upper receiver assembly for a firearm, the method comprising:
- forming an upper receiver defining a groove within an interior sidewall, wherein the groove defines a plurality of through-holes extending through the interior sidewall of the upper receiver to an exterior sidewall of the upper receiver, wherein forming an upper receiver further comprises forming a raised rail at the exterior surface of the upper receiver, wherein the raised rail is aligned with the groove;
- placing a cam race within the groove, wherein the cam race comprises:
- a body defining a slide face and an opposite rear face, wherein placing the cam race within the groove comprises placing the body within the groove;
- and
- a plurality of fastener pins extending away from the opposite rear face, wherein placing the cam race within the groove comprises placing one or more of the plurality of fastener pins through a corresponding through-hole;
- and
- securing the cam race within the upper receiver via one or more of the plurality of fastener pins.
