You've got a beautiful Model 1899 Krag carbine there! I've always been a fan of these carbines set with the headless cocking piece like yours has. The cleaning kit is a nice addition along with the rare front sight protector. If you had a period sling, you'd be all set! But, these "extras" on your Krag along with the correct carbine marked rear sight, add a bunch of value to your carbine. I would add that a nice bore is one of my big concerns, also.

So, great start on a wonderful Krag carbine. If you stick with us, we'll help you multiply that Krag collection which most of us have found out happens without much effort. (Almost on its own!)

That rear sight looks like it might have some black paint on it. I don't know for sure what it is but some acetone might take it off and clean it up easily without damage. Remove the sight from the carbine carefully first before putting any chemicals on it so as not to damage the wood stock at all. There are many ways to safely clean some of these problems without damaging the carbine.

Thanks for sharing and keep us informed as to how it shoots!
