Frequently Asked Questions

What is the Marlin Model 1917 Machine Gun?

The Marlin Model 1917 is a gas-operated machine gun, notable for its unique swinging lever action. It is a licensed copy of the Colt Model 1895/1914, which itself evolved from the original Colt Model 1895, famously nicknamed the 'Potato Digger'.

How does the Marlin Model 1917's 'Potato Digger' mechanism work?

Gas is tapped from a port under the barrel, pushing a swinging lever downward. This lever pivots and is connected to the operating slide, providing the force to cycle the firearm's internal components and chamber a new round.

Why is the Colt Model 1895 and its variants called the 'Potato Digger'?

The nickname 'Potato Digger' comes from the violent back-and-forth motion of the operating lever. If fired without a proper mount, the lever's movement could literally dig a hole in the ground.

What is the historical lineage of the Marlin Model 1917?

The Marlin Model 1917 is a licensed production of the Colt Model 1895/1914. This Colt model was an improvement upon the original Colt Model 1895, which was the first gas-operated machine gun developed by John Browning.
