Marlin Model 99 M1 semiautomatic rifle chambered for .22 LR. This rifle was made in 1971 in the U.S.A. The Marlin 99 M1 is a combination of the Model 99 and the M1 carbine. It features a shorter barrel and a large "one-piece" stock similar to that of an M1. If you are looking for a great collector piece that's a joy to shoot, this 99 M1 is a great buy. The stock has some wear marks and scuffs. The barrel has a couple small marks near the muzzle.
