A combustion powered tool for driving fasteners having a housing to house a main chamber. Within the main chamber is a power source having a combustion end and a lower end enclosed in the main chamber. A rod is driven by the combustion end of the power source. A device is provided for feeding fasteners sequentially for engagement with the rod. A nosepiece has a tool end, a workpiece end opposite the tool end, and depends from the lower end of the power source. The nosepiece is configured for receiving the rod from the lower end of the power source and for guiding the rod toward a workpiece. A workpiece-contacting element is slidably mounted on the nosepiece. Also provided is a protective shield for protecting the nosepiece and the workpiece-contacting element. The shield is constructed and arranged to define a cavity between the nosepiece and the shield, and is tapered from an upper end to a lower end.
