ABSTRACT:
We disclose a new switch-barrel system for firearms, particularly centerfire rifles, which permits the ready exchangeability of barrels upon a single action/stock assembly. Barrels may be quickly and easily exchanged under field conditions using a minimum of simple, lightweight equipment, without removing the action from the stock. Barrels of many different weights and calibers may be used on a single firearm, leading to great versatility. Barrels are free-floating in a manner similar to most benchrest rifles, ensuring uniform barrel harmonics upon firing. The system relies on a secondary set of fine-pitched threads and a locking ring to effect the securing of the barrel to the action, which acts to repeatably draw all barrels into invariable coaxial alignment with the action, thus insuring a return to essentially the same point of impact. The system is adaptable to a broad range of existing firearms, and does not require a proprietary action. It does not significantly alter the lines of fine sporting arms, and adds only a minimum of bulk. It does not require hardened setscrews or other securing devices which can easily mar barrel steel. It permits firearms to be broken down for transport in more compact containers, and is self-correcting for wear in the securing and headspacing relationships.
