This video explains the fundamental differences between open bolt and closed bolt firearm actions. Open bolt systems keep the bolt rearward until firing, offering advantages like better cooling and preventing cook-offs, making them common in machine guns. Closed bolt systems have the bolt forward with a round chambered, generally providing superior accuracy due to less moving mass during the firing cycle. The video also touches on manufacturing simplicity and historical ATF regulations regarding open bolt designs in the US.
