Abstract
The mechanism comprises a main frame () and its extension ('), which accommodate a barrel () with fixed mounting, a mobile bolt () and its guiding pin ensemble () and main spring () moving in the main frame (), a mobile mass () and its assembly of guiding pin (), push plate () and return spring (), and a mobile mass catch sear () and its spring (). The mobile mass pivots from a first position under the barrel to a downward position in reaction to the backward movement of the mobile bolt. The placement of the mobile mass in front of the chamber directs counteracting forces down on the barrel to prevent muzzle climb during operation.
