Abstract
An upper receiver is provided for cooperatively engaging a lower receiver, wherein the lower receiver includes at least a trigger and a lower hammer. The upper receiver includes an upper sear movable in response to movement of the lower hammer, thereby permitting an upper hammer in the upper receiver to actuate a valve in the upper receiver and pass a motive gas to a firing chamber and thereby expel a projectile through a barrel of the upper receiver.
Claims11
An upper receiver for cooperatively engaging a lower receiver having a trigger and a lower hammer, the lower hammer movable between a loaded orientation and a firing orientation, the upper receiver comprising:
- (a) an upper hammer movable between a cocked position and a firing position;
- and
- (b) an upper sear movable between a release position and a retaining position, the retaining position of the upper sear retaining the hammer in the cocked position, and the upper sear in the release position permitting movement of the upper hammer to the firing position, the upper sear moving from the retaining position to the release position in response to the lower hammer moving from the loaded orientation to the firing orientation.
A method comprising:
- (a) engaging an upper receiver with a lower receiver to form a gun and operably interconnect a trigger and lower hammer in the lower receiver with an upper hammer and upper sear in the upper receiver, wherein movement of the trigger to a firing position results in movement of the upper hammer from a cocked position to a firing position.
A method comprising:
- (a) releasing a lower hammer in a lower receiver by moving a trigger in the lower receiver from a non-firing position to a firing position;
- and
- (b) contacting the released lower hammer with a portion of an upper receiver to release an upper sear in the upper receiver to move an upper hammer in the upper receiver from a cocked position to a firing position.
