But what exactly is an AR-15, and why are they so common? The AR-15 was first developed as a semi-automatic rifle for civilians in the 1950s by Armalite, a US firm after which the "AR" is named.

The AR-15 isn’t just a rifle—it’s a triumph of engineering. Designed by Eugene Stoner, it revolutionized firearms with precision mechanics and unparalleled modularity.
