Abstract: Firearm bolt assemblies and firearms including the same are described. In embodiments the firearm bolt assemblies are configured to localize compressive forces applied during a transition from an initial position to a firing position to a first cam system on one side of the firearm bolt assembly, and to localize compressive forces applied during a transition from the firing position to the initial position to a second cam system another side of the firearm bolt assembly. Localizing the forces in that manner enables the use of a first cam system that is relatively robust compared to the second cam system.

Abstract: Firearm safing assemblies and firearms including the same are disclosed. In embodiments firearm safing assemblies include a safing sector with a track surface and a receiver door track. The receiver door track may couple to a receiver of a rotatable firearm, wherein the receiver includes a bolt track and at least a portion of the receiver extends coaxially about a first axis. The safing sector is configured to be at least partially disposed within the receiver door track and to move between a safe position and an armed position. In the safe position the track surface is out of alignment with and does not form part of the bolt track, whereas in the armed position it is aligned with and forms part of the bolt track.
