Patent ID: 7191774

Claim:
A toy air gun comprising: a cylindrical hollow barrel having a central axis and comprising: an open first end; a second end having a transparent central portion; a first section with a diameter adjacent to the open first end; and a second section with a diameter adjacent to the second end; a moveable member with a diameter less than the diameter of the second section of the barrel, fitted coaxially within the second section so that the moveable member is constrained to move axially along the barrel, and having a transparent central portion; and an elastic element for biasing the moveable member towards the first end, coupled to the moveable member and the barrel such that when the moveable member is pulled back against the elastic element and released, the moveable member moves coaxially along the axis of the barrel to force air to travel forward and out the open end of the barrel, and the entire length of the gun being transparent along the central axis, such that the transparent central portion of the second end of the barrel and the transparent central portion of the movable member forms a coaxial sight down the axis, allowing a user to aim the gun by sighting directly along the central axis of the gun barrel through the transparent central portion of the moveable member and the transparent central portion of the second end of the barrel.
