Claim Text:
1. A gas operated firing assembly for a firearm, the assembly comprising; a bolt carrier having a longitudinal axis; a surface defining a vertical gas port orthogonal to the bolt carrier longitudinal axis; the vertical gas port in fluid communication with a gas block forward of a chamber of the firearm via a gas tube when the firearm is assembled; a surface of the bolt carrier defining a lateral valve housing orthogonal and intersecting the vertical gas port and orthogonal to the bolt carrier longitudinal axis; a valve core having a substantially cylindrical outer surface in close sliding fit to the valve housing so as to rotate therein without appreciable gas transfer there between the cylindrical outer surface and the valve housing; and the valve core having a surface defining a port at least partially and selectively controls flow thorough the vertical gas port.
