THIS IS A MODEL 1899 SPRINGFIELD ARMORY Krag Carbine ( it has the 22" barrel, but the wrong stock) in was assemble in 1900 per two sources I have used "The American Krag Rifle and Carbine " by Joe Poyer and Springfield Armory Museum website by the National Park Service. The carbine is 41 inch's and weights 7 lbs. 13 oz. Serial # is 2829xx. IT WILL need a FFL or CR. Barrel is Fair to Poor. Wood is wrong. Functions well, I have shot it years ago. Rear Sight may or may not be correct. Metal not that bad for a carbine made in 1900! Thanks for looking! 

"The Springfield Model 1892–99 Krag–Jørgensen rifle is a Norwegian-designed bolt-action rifle that was adopted in 1892 as the standard United States Army military longarm, chambered for U.S. caliber .30-40 Krag cartridges. All versions and variants were manufactured under license by the Springfield Armory between 1892 and 1903 and famously served as the longarm during the Spanish–American War.

Although "Krags" were popular, unique and efficient, the side loading gate mechanism was slow and cumbersome to reload in combat compared to the clip loaded Spanish Mausers the Krag was up against. Thus, the U.S. Krag was replaced beginning in 1903 with the introduction of the M1903 Springfield rifle, which was essentially a copy of a Mauser, although some design elements of the Krag remained, such as the cocking piece.

American Krags are the most plentiful and affordable of all three Krag variants, although many are sporterized, and they remain popular with collectors today."
