There’s a guy (yogi89) on Reddit who 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 from 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, no less) and we’re amazed it was granted. Anyway, it took him three months to finish and the magazine is removable.
