It's a Discovery Channel TV show, and Discovery is famous for over-dramatizing daily activities and jobs. As was said earlier, how many people would stay tuned to the show if all they ever did was convert and modify Saiga's and AR's.
The same goes for Orange County Choppers. Who would watch the show if all they did was build their production bikes, and not the un-rideable rolling advertisements they are now famous for. Or how about Pawn Stars? It's "reality TV", and there's nothing real about it.
