Abstract

An interchangeable barrel assembly for a firearm including a novel barrel and tool assembly which are used with a receiver having an open aft end. The tool assembly is configured to be inserted into the receiver open aft end so as to engage the aft end of the barrel. Torque applied to the tool assembly thereby transfers torque to the barrel without transferring forces to the action. This enables the same action to be used with different barrels and the barrel may be removed without removing the receiver or other components of the modular chassis or accessories mounted thereon. Additionally, standard torque may be applied to the barrel for connection to the receiver and firearm precision is maintained.
