My experience with LEGOs is primarily building Star Wars ships with my son. For a number of years we would travel to his grandparents house for Thanksgiving, go looking for a large model to build on Black Friday, and spend the weekend working on it. The LEGO enterprise has continued to expand and grow, and covers many more areas now than mundane earthbound transportation and the Millenium Falcon.
Although some will not be happy that one can build guns out of LEGOs, I won't address that here. Judging by my experiences with my son, guns can be made out of almost anything! The four guns that are presented in the book are the Desert Eagle, AKS-74U, Jungle Carbine, and SPAS 12. The author makes clear that though the cover states these are working replicas of the guns, "working" in this instance means able to shoot LEGO bricks propelled by rubber bands. "Working" also means that some of the functional parts of a gun are modeled, including a safety mechanism, magazine, movable trigger, and firing mechanism and slide. The design of the LEGO guns models the actual gun in amazing detail.
The building instructions are largely pictorial, with occasional textual directions added for clarity. The illustrations are black and white, which can make interpretation of some of the drawings challenging but not impossible. But the cost of making color illustrations for a book this size (353 pages) would be prohibitive. The book contains advice about building techniques, and gives several sources for obtaining the necessary LEGO pieces to complete the projects.
This is a book that accomplishes its aims well, and would make a great gift for certain children. An occasional adult mght also enjoy it. The pictorial guides to construction are particularly well suited to the target audience, in this case, a picture is worth more than a thousand words! Recommended.
