I have seen at least two that have broken one at the take down pin and the other where the buffer tube mates to the lower. Both had less than 500 rounds through them. As for steel and wood if I thought that way I would not fly in an alloy and carbon fiber airplane only a Wright brothers design with wood, canvas and steel. Plastic used in the way it is used in some guns with reinforcement is fine but without the reinforcement and where it is, NO. Hand guards, stocks and pistol grips are ancillary and are readily accepted and replace easily and do not affect the workings of the rifle ie fire control.
