摘要： A take-down rifle which permits easy removal and reassembly of the barrel to the receiver portion of the rifle and incorporating a system for effectively accommodating for wear in the mating parts thus providing for proper alignment between the rifle's two main components. The system includes a barrel bracket secured to the forearm, an adjustable collar threaded on the receiver end of the barrel and in contact with the barrel bracket, and the bonding of the barrel to the forearm by means of a low durometer elastomeric adhesive. Adjustment for wear can be made by turning the adjusting collar in a direction to cause the barrel to move in a direction away from the barrel bracket which accommodates for any thread wear between the receiver and the barrel.
