These guns are very delicate.  There are 2 springs and that stresses everything twice as much as what a typical bb guns are subjected to.  The metal is the same thickness (gauge) as typical bb guns when it should have been made of a heaver gauge material.  We have seen these come in for repair with the broken stocks, The receiver actually split or broken in half as well as the rear of the barrel lower frame split or broken in two.  We recommend these not be fired or at least not be fired very much or you will find yourself holding 2 halves of the gun.
