SLOWEST Full Auto Ever?!?!
The M3 Grease Gun, a historically significant and economical firearm, is showcased for its surprisingly controllable full-auto fire. Despite its age, its slow rate of fire (around 450 RPM) makes it manageable, even compared to modern firearms. The video highlights its simple stamped metal construction and open-bolt operation, noting the M3A1's simplified thumb-cocking mechanism.
