A "falling block" is a type of firearm action commonly used in rifles and shotguns. In this mechanism, the barrel and action are hinged together, allowing the barrel to pivot downward when the action is opened. This design facilitates easy loading and unloading of cartridges, making it user-friendly for shooters. When the shooter closes the action, the barrel returns to its original position, locking securely in place. This system is often found in break-action firearms, which are known for their simplicity and reliability. The falling block design is appreciated for its strength and accuracy, making it popular among hunters and sport shooters.
