It takes some gun-smith skills and equipment to fit a Criterion barrel to a Krag action.

The Criterion Chamber requires finish reaming (for head-space) and proper 'timing' of threads, so that the factory 'extractor notch', rear-sight holes and 'flat' for front-sight base end up in correct orientation.

You have to provide a front-sight base to be fitted and brazed or silver-soldered on the barrel 'flat'.

Criterion barrels come drilled and taped with rear sight holes. They use a different thread. Original Krag rear-sight screws won't work.

It is likely the CMP has a lengthy wait time.

A replica front-sight installation will look something like the attached photo.

Hopefully, somebody responds that has direct experience with a Criterion barrel Krag installation.
