    • A gun with two barrels of different calibers wherein both barrels have a repeater mechanism, manual or automatic, and wherein the weapon has a barrel-selector mechanism which selectively, as desired, brings one barrel into an operative state while at the same time putting the other barrel in an inoperative state. The breech block for the respective barrels are joined together via a cam on the breech block, such that the two breech blocks together constitute a cam mechanism which permits movement of the other breech block toward and away from the first breech block transversely of the barrels, and that the two breech blocks, during repeater-action of the weapon, move together and in parallel in the longitudinal direction of the barrels. The interconnected breech blocks thus together and synchronously lock the two breech blocks in their forward positions.
    • 具有两桶不同口径的枪,其中两个桶具有手动或自动的中继器机构,并且其中所述武器具有桶选择器机构,其选择性地根据需要将一个桶带入操作状态,同时将 其他桶处于不工作状态。 用于相应桶的后膛块通过后膛块上的凸轮连接在一起,使得两个后膛块一起构成凸轮机构,该凸轮机构允许另一个后膛块朝向和远离第一枪膛横向移动, 并且在武器的中继动作期间,两个后膛块在筒的纵向方向上一起移动并且平行。 因此,互连的后膛块在一起并同步地将两个后膛块锁定在它们的前部位置。
