Bolt repositioning device for firearms.

摘要

A semiautomatic firearm including a recoil spring acting on the bolt for closing the breech after the ejection of the case. The repositioning device includes an auxiliary resilient member which cooperates with the recoil spring, so that although a low-rigidity spring suitable for weak cartridges is used, the weapon works correctly even when firing powerful cartridges. The device thus allows to use a wider range of cartridges and reduces the negative effects of recoil. <IMAGE>
