Well the serial number is out side of the known range for 1898 carbines. The stock is correct carbine stock but the sling bar and ring were not installed on long forend carbine stocks as long stock carbines were ment to be carried in saddle scabbards. The front sight has Bubba written all over it!! (Even though it might have been a correct Krag sight at one time!!)I would say not a carbine. Should be a fun shooter and a handy hunting rifle though
