As the second most produced personal firearm of the last few centuries, the 100 million or so users of the Kalishnikov design and its variants [AK47, AKM, RPK light MG, Valmet and Galil modified variants and countless knockoff copies, PK and PKM machineguns and even the AKSU *machinepistol* variants] appear to agree with you. Stoner's AR-15/M16 design comes in 4th, behind Great Britain's *Brown Bess* flintlock musket and copies thereof, which numbered some 15 million in their day.
The estimated 120 million Mauser-action rifles in their various models and types continue to hold first place, slightly ahead of MikTim Kalishnikov's brainchild. But a few more years of production, still during his lifetime, may tip the balance. That's a LOT of shootin irons out there....
Including mine.
