Is This the Quietest Rifle in History?

The De Lisle carbine is one of the quietest firearms ever created, purpose-built during World War II for clandestine missions. Chambered in .45 ACP and equipped with an integral suppressor, it allowed British commandos to operate with near-total silence.

In this video, we put the legendary De Lisle to the test on the range. Can you actually hear it when it fires? How effective is the design compared to modern suppressed rifles? We’ll explore its history, mechanics, and most importantly—just how quiet it really is.

Join us as we test one of the rarest and most fascinating rifles of WWII.
