There’s a guy (yogi89) on Reddit that used his time in shop class more productively than most. Instead of building a coffee table or a chair, he decided to make a SCAR-L out of wood, and he did it remarkably well. There are more pictures here. He says he sought and received permission to build it in school (high school) – and we’re amazed it was granted. Anyway, it took him three months to finish and the magazine is removable. Simply amazing.
