Abstract
A sharpshooting nail gun capable of driving a nail into an intended spot. The nail gun includes a bit guide having an injection groove through which a nail and a drive bit pass. A contact arm is movably supported to the bit guide. The contact arm has a lower tapered end portion abuttable against a wall or attachment member, and an upper portion engageable with a trigger. When the contact arm is biased toward the wall, the upper portion is disengaged from the trigger for allowing the trigger to be manipulatable. The lower portion of the contact arm protrudes from a lower end of the bit guide, and is provided with an injection bore extending in alignment with the injection groove.
