Patent ID: 8826576

Claim:
An apparatus, comprising: a bolt assembly comprising: a bolt head, a bolt face, an extractor and a first and second ejector, wherein the bolt head defines a first and second channel that receive the first and second ejectors, wherein the bolt head defines a longitudinal axis, an extractor plane and a first and second radial ejector plane, wherein the extractor plane substantially bisects the extractor, wherein the first ejector plane substantially bisects the first channel, wherein the second ejector plane substantially bisects the second channel and wherein the longitudinal axis lies on each of the extractor plane and the first and second ejector plane; wherein the first and second channels are positioned on opposite sides of the extractor plane; wherein a first angle between the extractor plane and the first radial ejector plane is between approximately 3π/9 and 7π/9 radians; wherein a second angle between the extractor plane and the second radial ejector plane is between approximately 3π/9 and 7π/9 radians; and wherein the extractor is constructed and arranged to interface with a shell casing in a chamber and to extract the shell casing from the chamber and wherein the first and second ejectors are constructed and arranged to push the shell casing away from the bolt face thereby pivoting the shell casing substantially about the extractor.
