Model 1899 Krag

[pvt81pvi]

I recently acquired this Krag carbine. The receiver is marked Model 1899, barrel is 22” long and was turned down at the muzzle for a 1903 front sight. There are no cartouches on the stock that I can find, and the forend was not cut down (no plug in the end). The buttstock has 3 cleaning rod holes present. It also has a 1901 sight, but I cannot find a “c” stamped on it. Serial number is 280510. What do I have, and is there a SRS available? Thanks in advance!
