Abstract
The present invention is directed to a revolver, where headspace is achieved differently and separately from the barrel, where [a cartridge is placed in the cylinder] and where that headspace is a function of caliber and varies per caliber/cylinder. The system of the present invention links a unique barrel and cylinder relationship so that each may be exchanged with the other set on the same frame. A tension ring is used to threadedly engage the interchangeable barrel relative to the interchangeable cylinder and revolver frame such that the predetermined headspace is preserved. And all being fit to differing headspace points within the single revolver frame. Each could be numbered so that confusion of which cylinder with which barrel be reduced.
Claims6
An adaptable revolver, comprising:
- a. a revolver frame;
- b. an interchangeable cylinder chambered to receive ammunition cartridges of a preselected caliber and rotatably mounted on the revolver frame with a predetermined headspace characteristic of the preselected caliber therebetween;
- c. an interchangeable barrel bored to the preselected caliber and threadedly engaged through the revolver frame in a defined spatial relationship to the cylinder;
- and
- d. a tension ring adapted to threadedly engage the interchangeable barrel relative to the interchangeable cylinder and revolver frame such that the predetermined headspace is preserved.
