ABSTRACT:
An inspection device for evaluating the inside surface of a barrel of a firearm is disclosed. The inspection device comprises a casing, a lightbulb and battery contained within the casing, and a light diffusion assembly. The light diffusion assembly includes an annular portion connected to one end of the casing through which light may pass, and an opaque cap portion connected to the annular portion through which light may not pass. When the inspection device is introduced into the chamber of a firearm into which ammunition is normally loaded, the lightbulb begins to burn. Light is directed by the lightbulb substantially through the annular portion of the light diffusion assembly to fall radially on the interior surface of the barrel. Visual inspection of the barrel is thereby facilitated without temporarily blinding the eyes of an observer. Also disclosed is a method using this inspection device for inspecting the barrel for residue or defects.
