I put it down to Youtubers who spunk £1000's into a silverback or VSR, and then edit gameplay to make it look like they shoot lasers, rather than the truth of sitting in a bush, firing 10 rounds to hit the target, then spend the afternoon in the safe zone wondering why it's not working.
People watch it, buy a novitwat or cyma/well/jg and a scope and wonder why they're not doing it, and sell it after 2 games.
