Patent ID: 7913410

Claim:
A device for measuring the overall length of a firearm consisting: an elongated measuring base having a ruler having at least one sequence of linear measuring indicia thereon extending from one end of the measuring base parallel to the axis of elongation that measures the overall length of the firearm and further having a raised slotted rail extending substantially the length of the measuring base parallel to the axis of elongation, a fixed end back plate extending upward from said one end of the elongated measuring base for placing one end of the firearm and; a fixed back plate extending upward along the length of the measuring base, located perpendicular to the fixed end back plate, and; a measuring movable sliding plate connected between the ends of the elongated measuring base for placing the other end of the firearm and to accommodate measuring a variety of firearm lengths, said measuring movable sliding plate consisting; a slight recess that frictionally engages with the raised slotted rail, a fixed tailpiece that ensures engagement with the raised slotted rail and extends perpendicular to the movable sliding plate; an index panel extending upward from said movable sliding plate and having an indicating relationship with said at least one sequence of measuring indicia located along the length of the elongated measuring base.
