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

Looks like you have an 1894 Rifle that has been modified to look like a Carbine.  The barrel was most likely cut and recrowned.  The front sight is an aftermarket banded front sight.  The stock is a rifle stock that has been cut to resemble a carbine stock.  This was all done most likely to make it more suitable for hunting.  Looks like it's in pretty good condition too!  How does it shoot?  Sporters like this make great shooters!
