Operating system for reloading firearms combining a gas piston system and an external manually actuated mechanical linkage

Abstract

An Operating System for firearms combining a direct drive gas piston system, functioning in conjunction with a linkage mechanism operating within a structural tube, enabling the use of a frontal charging handle or a sliding handguard allowing a frontal actuated, ambidextrous, non-reciprocating charring operation. The operating system is conceived to be easily retrofitted in M16 rifles without performing any machining operations. The artifact partially comprises affixing supports, a structural tube to constrain and align the actuating components, a securing frontal gas block, a regulated direct gas piston including an independent push bar with alignment rings, springs, and freely displacing parts with lateral projections connecting with the exterior handle or hand guard actuator. By enabling to use the firer's supporting hand while charging, it solves complicated ergonomic maneuvers required to charge with the original M16 T handle, improves rifle cleanliness, and reduces the crucial time to get back on target.

What I claim is: 
     
         1 . A combined operating system for reloading firearms by means of a mechanism jointly operating a gas-piston charging system, and an external, manually actuated, mechanical linkage mechanism charging system. 
     
     
         2 . The operating system of  claim 1  wherein said manually actuated, mechanical linkage mechanism charging system includes a linearly operated handle. 
     
     
         3 . A factory made firearm including said operating system of  claim 1 . 
     
     
         4 . A retrofitted firearm including said operating system of  claim 1 . 
     
     
         5 . A factory made firearm including said operating system of  claim 5 . 
     
     
         6 . A retrofitted firearm including said operating system of  claim 5 .
