Welcome, Flintstone, to KCA. We love Krags here and love helping other people enjoy their Krags as much as we do!

Your Krag serial number 210582 was made in May 1899. It is well in the range of Krag rifles, so, I would say it has had the regular 30 inch barrel cut down to carbine length 22 inches or has had a carbine length barrel switched onto your rifle.

Pictures of different parts of your Krag sporter will help us identify these details better. Need pictures of the receiver markings, the front and rear sights and other markings that might be present. Also overall pictures can show how it looks.

Thanks and get pictures uploaded if able. Any questions, let us know.
