This video breaks down the fundamental differences between operating systems and locking systems in firearms. The locking system is responsible for sealing the breech during firing, employing mechanisms like tilting bolts, rotating bolts, and roller locking. The operating system, on the other hand, handles the unlocking process after firing when internal pressure has safely decreased, utilizing systems such as long and short gas pistons or long and short recoil. Blowback mechanisms are presented as a unique case where a single system uses inertia for both locking and unlocking. The video aims to educate viewers on these core mechanical principles for a better understanding of how firearms function.
