In recent years, the usage of AR-15 has been on the rise, and nothing is stopping it at all. In general, AR means “Armalite Rifle.” It is not an Assault Rifle, as you think. Yes, this is a famous misunderstanding. Initially, the rifle was made by Armalite. But as Financial troubles started to emerge, the company was forced to sell their rights to Colt. Now Colt has been making these semi-automatic rifles in vast numbers. However, AR Gun Builders seem to create customized versions, which get recognized in the end.
