Actually...No. Thery were all marked "carbine" until Walmart had one of thier special runs made with a stainles model having a 22" bbl. The recievers were marked "rifle". I'm not 100% but believe some of the current cataloged models are so marked as well depending on the bbl length. Ruger makes the standard 18 1/2" carbine that most are well aware of, the RR model which has a 20" bbl and the Compact which has a 16 1/8" bbl. Which moel you choose depends on what you want. Leave it as is...get the model you want it as. Buying as a basis to build into something different, buy the least expensive one you find.
