Arizona Travis:  Welcome to the KCA Forum.  You are mighty fortunate to inherit a family heirloom from your Grandfather.  It appears you have a cut-down model 1898 rifle in a very desirable model 1898 carbine stock.  The sling swivels are not original to the Krag.  It appears your barrel has been dove-tailed for a commercial rear sight which is missing.  Your 'banded' front sight looks like it might be a re-shaped 1903 Springfield sight.  If your bore and chamber are cleaned and in decent condition and your bolt's locking lug is 'ok' you are probably 'good to go'.  Just get a rear sight that fits the barrel dove-tail.  If you have an area gunsmith that is competent with older arms, have him check it out and put on a rear sight.  (I took the liberty of playing with your picture).
