The Remington Model 11-48 was a major milestone in semi-automatic shotgun design, introduced in 1949 to replace the legendary Model 11. It holds a unique place in firearms history as the first shotgun designed by Remington to transition from expensive, old-world machined steel manufacturing to modern, streamlined production techniques.Designed by legendary firearms engineer John Moore, it combined the reliable mechanical operating cycle of the past with the sleek, rounded aesthetics of the future.Streamlined Design and MechanicsThe Same Core Action: Like the older Model 11 and Browning Auto-5, the 11-48 operates on John Browning's long-recoil system. When fired, the entire barrel and bolt lock together and move backward inside the receiver before unlocking to eject and reload.No More "Humpback": Unlike the blocky, squared-off "humpback" receiver of the Model 11, the 11-48 introduced a beautifully streamlined, rounded receiver shell. This sleek silhouette paved the way for the look of almost every modern semi-auto shotgun that followed.Stamped Steel Revolution: Remington designed the 11-48 using stamped steel internal components. This drastically reduced manufacturing costs and weight, resulting in a lighter, faster-handling field gun.Friction Ring Adjustments: Just like its predecessor, the 11-48 uses a brass friction piece and steel rings on the magazine tube. You must arrange these rings correctly depending on whether you are shooting heavy magnum loads or light target loads to ensure reliable cycling and prevent cracked wood.
