Ruger Deerfield Carbine
Centerfire semi-automatic rifle
The Deerfield Carbine or Model 99/44 is a .44 Magnum semi-automatic rifle produced by Sturm, Ruger & Co. It uses a rotating-bolt short-stroke gas-piston.[2] It was introduced in 2000[3] and discontinued in 2006.[2]
The Deerfield Carbine replaced the earlier Ruger Model 44 Deerstalker rifle first produced in 1961 and dropped from the Ruger lineup in 1985 due to high production cost.[2][4] The Deerfield is a brand new design and has little in common with the Model 44. While the Model 44 featured a solid-topped receiver, the modern Deerfield Carbine has an open-top design more resembling the M1 Carbine,[5] which is stronger and easier to make.[3] The Deerfield also uses a rotary magazine similar to that used on Ruger's .22 LR 10/22 rifle,[5] whereas the Model 44 was fed via a fixed 4-shot tubular magazine.[6]
