Abrégé

An improved action for a bolt action rifle. The action includes a receiver containing a bolt; the bolt having two to three locking lugs surrounding a bolt face; and a threaded insert that joins the rifle barrel to the receiver. The insert also includes a series of locking lugs that mate with the locking lugs on the bolt. The position of the insert lugs relative to the barrel will position the bolt face relative to the barrel's chamber when the bolt is closed. Thus, the insert and barrel can properly set the rifle's headspace. The insert and receiver are preferably each provided with a locking lug, that serve to align the axes of the insert and receiver. The threads of the insert and the barrel are co-axial which serves to align the axes of the insert and barrel. Thus, assembled, the receiver, insert and barrel will be substantially co-axial.
