1858 new model army spare cylinders

[coal]

I've been looking around for spare cylinders for my black powder remington revolver I got recently. from what I can tell from the markings it's a 1977 armi sport but I can't really find any cylinders for it. can I get a uberti cylinder or are there slight differences in manufacture I'd so of anyone knows where I can get spare cylinders lmk please

Dixie Gun works or Taylors maybe.

I would see if someone close by has an Uberti or Pietta and check the fit.

Pietta cylinders are just a bit longer than Uberti. Uberti is very very close to the originals. Got a set of calipers so you can give us measurements off your gun?

I measured 3 different cylinders one from an original New Model Army.

Interestingly, the bore centerline is close enough that I think you could probably interchange cylinders between all of these without real issue, if the Pietta cylinder wasn't too long to fit in a Uberti or Original gun. Assuming the Cylinder orientation to bolt lockup is the same.
