  • said quick coupling device comprising a hollow body, which is fixed to said firearm body, and an elongated body, which is integral with said stock and can be at least partially inserted in said hollow body;

    said quick coupling device further comprising an interference member adapted to lock said elongated body in said hollow body in a locking position, said interference member comprising a piston which moves in opposition to a force exerted by a contrast or compression spring in a seat formed in said elongated body, said piston having an end adapted to engage a hole formed in said hollow body, in said locking position said contrast or compression spring pushing said piston into a position for engaging said end in said hole of said hollow body, thereby preventing the movement of said elongated body in said hollow body;

    said interference member being movable from said locking position to a release position in which said elongated body is movable and can be extracted from said hollow body, said release position being obtainable by pressing on said end of said piston, overcoming the force of said contrast or compression spring and disengaging said end from said hole, thereby allowing a sliding of said elongated body in said hollow body and a disconnecting of said stock from said firearm body, said end of said piston having a recess configured to accommodate a tip of said stem of the cocking handle for disengaging said end of said piston from said hole.
