I would recommend you enjoy this 'sportered' Krag as it is. Save your money and buy a nice condition, as issued, Rifle or Carbine, if you find you want an original. This will prove more cost effective.

Invest $20 in Joe Poyer's book, "The American Krag Rifle and Carbine". It will answer a lot of your questions and increase your enjoyment of your Krag.

If the bug really bites you, Franklin Mallory's, "The Krag Rifle Story", 2nd edition and Brophy's, "The Krag Rifle", are nice references.

Krags can be a bit of a jungle with a lot of 'cheats' or ill informed sellers. Arm yourself with knowledge. The Guys on this Forum are great!
