Abstract
A power actuated tool ( ) for driving a fastener into a substrate such as steel or concrete, comprises a housing ( ), a barrel assembly ( ) mounted to the housing, and a piston displaceable within the barrel assembly upon firing of the tool to drive a fastener from the forward end ( ) of the barrel into the substrate, at least a forward end of the barrel assembly being mounted for axial movement relative to the housing whereby firing of the tool requires the forward end ( ) of the barrel assembly to be pressed against the substrate to cause retraction of the forward end relative to the tool housing. A telescope shroud ( ) surrounds the forward end of the barrel assembly to at least partially suppress noise emission resulting from firing of the tool.
