It is not a bad looking job, but your muzzle-crown and front-sight attachment look "non-Armory" to me.
All of the finish has been removed from your front-sight blade and the cross-pin is flattened, so things have obviously been taken apart after it became civilian property.
Cleaning the 'brazing' will show clearly the quality of the front base attachment. Springfield Armory work made the front-base appear to be 'part of the barrel'.
The 22" barrel-length is arrived at by measuring with a cleaning-rod, inserted at the muzzle and coming to rest against the 'closed' bolt-face.
FWIW - I have a model 1899 carbine action that has a barrel with a 'banded' commercial front-sight. If measured on the outside the barrel appears to be 22 inches long, but when measured with a rod, it is 22 and 1/8 inches long.
This reveals the barrel to actually be a shortened Kragrifle barrel.
