Hi!  Welcome to the forum, and to the wonderful world of Krags!

Pictures would definitely help with identifying what you have.  A great many Krags were sporterized, and if your barrel has been cut, returning it to original condition would be difficult.  What rear sight do you have, and is there an upper handguard?  There is a picture page on this site where you can identify your rear sight, handguard, etc.

How did you measure your barrel?  The proper method would be to measure from the closed bolt to the muzzle with a cleaning rod.  A standard infantry rifle will be 30 inches, and a carbine will be exactly 22 inches.  If your front sight is dovetailed and brazed in place, it could be a standard carbine barrel... but again, it should be 22 inches. 

Also, a carbine stock will end just ahead of the rear band, however, a great many stocks were cut off to make them appear as carbine stocks.  Again, pictures would be a huge help in identifying what we're looking at.
