1. A bolt action firearm comprising:
- a chassis;
a receiver located along the chassis;
a barrel assembly mounted to the receiver and defining a chamber of the firearm adjacent the receiver, wherein the barrel assembly comprises an interchangeable barrel assembly releasably mounted to the receiver; and
an interchangeable bolt assembly having a bolt body slidably received within and movable along the receiver and defining an axial bore extending therethrough from a distal end to a proximal end, the interchangeable bolt assembly operable within the receiver for chambering and ejecting ammunition cartridges, the interchangeable bolt assembly including an interchangeable bolt head received within the axial bore at the proximal end of the bolt body and engaged by a removable locking member to releasably lock the interchangeable bolt head within the bolt body; and
a firing pin assembly received along the axial bore of the bolt body through the distal end thereof, the firing pin assembly having a firing pin that is extensible through a firing pin bore of the bolt head;
wherein the firearm can be reconfigured to be operable with ammunition cartridges of different calibers or sizes by interchanging the barrel and bolt head without having to replace the firing pin assembly to adapt the firearm to fire different caliber or size ammunition.

4. A bolt action firearm comprising:
-
a chassis; a receiver located along the chassis; a firing pin; a barrel assembly mounted to the receiver and defining a chamber of the firearm adjacent the receiver, wherein the barrel assembly comprises an interchangeable barrel assembly releasably mounted to the receiver; and an interchangeable bolt assembly having a bolt body slidably received within and movable along the receiver and defining an axial bore extending therethrough from a distal end to a proximal end, the interchangeable bolt assembly operable within the receiver for chambering and ejecting ammunition cartridges, the interchangeable bolt assembly including an interchangeable bolt head received within the axial bore at the proximal end of the bolt body and engaged by a removable locking member to releasably lock the interchangeable bolt head within the bolt body; and at least one transverse locking bore formed in each of the bolt head and bolt body, and wherein the locking member comprises a locking pin adapted to be received within the at least one transverse locking bore of each of the bolt head and bolt body to lock the bolt head to the bolt body, and configured to enable passage of a portion of the firing pin therethrough; wherein the firearm can be reconfigured to be operable with ammunition cartridges of different calibers or sizes by interchanging the barrel and bolt head to adapt the firearm to fire different caliber or size ammunition.

5. A firearm comprising:
-
a receiver; a chassis; a barrel assembly connected to the receiver and defining a chamber adapted to receive an ammunition cartridge therein; a fire control including a trigger for initiating firing of the ammunition cartridge; a magazine mountable within the chassis in communication with the receiver for supplying ammunition to the chamber; an interchangeable bolt assembly comprising a bolt body received within and movable along the receiver and having an axially extending bore therethrough, and an interchangeable bolt head received within the bore of the bolt body and releasably engaged by a transversely extending locking member to secure the bolt head within the bolt body, the bolt head having a firing pin bore defined therethrough; and a firing pin received along the bore of the bolt body and movable through the locking member and into the firing pin bore of the bolt head; wherein the locking member is removable from the bolt head to enable removal of the bolt head from the bolt body as needed to effect a change in caliber or size of ammunition fired by the firearm. - View Dependent Claims (6, 7, 8, 9)
