What you're looking at is a 125-piece puzzle block that, when disassembled and reassembled properly, becomes a .45-caliber firearm with all the accouterments, including laser sight.
"Michigan machinist GarE Maxton makes many different types of interlocking solid puzzles of this type, this time, he made a Puzzle Pistol, a single shot 45 caliber muzzle loading pistol, called the Intimidator. The Intimidator Puzzle is composed of over 125 pieces made from brass, bronze, copper, aluminum, magnesium and steel. Once diassembled, about 20 of the pieces can be recombined to make a functioning single-shot pistol. Other parts of the puzzle separately and securely store "a customized set of tools, all necessary hardware, 45 caliber bullets, a standard sight, a laser sight, a cannister containing black powder pellets, a secure storage area for 209 shotgun primers, a spent primer removal tool and a ramrod for loading the bullets."
