The Remington Model 11-48 is a semi-automatic shotgun manufactured by Remington Arms as the first of its "new generation" semi-automatics produced after World War II.[1] Released as the replacement for the Remington Model 11, it was manufactured from 1949 to 1968 and was produced in 12, 16, 20 and 28 gauge and .410 variations.

The Model 11-48 is a long-recoil operated semi-automatic shotgun based on the Model 11, itself based on an 1898 design by John Browning. Shells are stored in a tubular magazine under the barrel. When a chambered shell is fired, the barrel and bolt recoiling together (for a distance greater than the shell length) re-cock the hammer, eject the spent shell, and feed another shell from the magazine into the action.

Very nice gun has an adjustable choke for multi-platform uses…come see to appreciate.
