Abstract
A cam pin configured to be moveably constrained within a cam slot of a firearm bolt carrier and configured to be operatively connected to a firearm bolt, the cam pin having a cam pin shaft with a firing pin opening. The cam pin head of the cam pin is configured to contact the upper receiver via a cam pin head contact surface that has a reduced contact surface area or length.
Claims20
A cam pin configured to be moveably constrained within a cam slot of a firearm bolt carrier and configured to be operatively connected to a firearm bolt, wherein the cam pin comprises:
- a cam pin shaft comprising a firing pin opening with a firing pin opening central axis and configured to receive a firing pin therethrough substantially along the firing pin opening central axis;
- and
- a cam pin head at an end of the cam pin shaft configured to slide within an upper receiver slot and contact the upper receiver via a cam pin head contact surface, wherein cam pin head contact surface includes at least a curved surface portion with a major axis that is perpendicular to the firing pin opening central axis.
A cam pin configured to be moveably constrained within a cam slot of a firearm bolt carrier and configured to be operatively connected to a firearm bolt, wherein the cam pin comprises:
- a cam pin shaft comprising a firing pin opening configured to receive a firing pin therethrough;
- and
- a cam pin head at an end of the cam pin shaft configured to slide within an upper receiver slot and contact the upper receiver via a cam pin head contact surface, wherein the cam pin head contact surface has a curved portion that reduces a contact surface area that contacts the upper receiver, wherein the contact area is 0.00196-0.0190 inches squared.
A cam pin configured to be moveably constrained within a cam slot of a firearm bolt carrier and configured to be operatively connected to a firearm bolt, wherein the cam pin comprises:
- a cam pin shaft comprising a firing pin opening configured to receive a firing pin therethrough;
- and
- a cam pin head at an end of the cam pin shaft configured to slide within an upper receiver slot and contact the upper receiver via a cam pin head contact surface, wherein the cam pin head contact surface has a curved portion so that a contact area length that contacts the upper receiver at a given time is reduced, wherein the contact area length that contacts the upper receiver is 0.0245″-0.2375″.
A cam pin configured to be moveably constrained within a cam slot of a firearm bolt carrier and configured to be operatively connected to a firearm bolt, wherein the cam pin comprises:
- a cam pin shaft comprising a firing pin opening configured to receive a firing pin therethrough;
- and
- a cam pin head at an end of the cam pin shaft configured to slide within an upper receiver slot and contact the upper receiver via a cam pin head contact surface, wherein the cam pin head contact surface has a curved portion that reduces a contact area length that contacts the upper receiver, wherein the contact area length is 0.001″-0.0245″.
