Ruger Deerfield Carbine

The Deerfield Carbine or Model 99/44 is a .44 Magnum semi-automatic rifle produced by Sturm, Ruger & Co., introduced in 2000. The rifle is based on the earlier Ruger Model 44 rifle first produced in 1961, which had been dropped from the Ruger lineup in 1985 due to production cost; the 1961-1962 Model 44 was marked as the Deerstalker. The rifle was reclassified as a carbine and renamed Deerfield due to the notable lawsuit brought by the Ithaca Gun Company. The Model 44 featured a solid-topped receiver, while the modern Deerfield has an open-top design more resembling the M1 Carbine, which is stronger and simpler. Unusually for a modern centerfire firearm, the Deerfield uses a rotary magazine similar to that used on Ruger's .22 LR 10/22 rifle.
