12-calibre rifle and the like designed to rationalize the selectivity of six different physical operating principles

摘要

This innovation, which is designed to broaden in qualitative terms technology in the area of weapons, is based on rationalization of the mechanical organisational structure so as to offer new fundamental features which widen the range of applications. In order to overcome the problems which still exist in this sector, the mechanical selector of the weapon is operated manually so as to select six different and mechanically interdependent options which are able to satisfy the requirements during practical use. Operation of the various steps is achieved by positioning the selector which acts as an assembly bush: position A: automatic with long recoil position A: pump with long recoil position B: automatic with short recoil C: automatic, gas intake D: pump, fixed barrel E: automatic, inertial IMAGE
