If you do a SEARCH on the Civil War boards for any discussions of the Armi Sport M1861 Springfield or "Richmond particularly "how to" and "why" type discussions.. the same applies to the Richmond Carbine as it is just a reworked rifle-musket and the same issues apply.
On the other hand, Pedersoli tends to normally, usually, generally (NUG) be a notch up of the best of the worst ladder as they NUG hold to a relatively higher concept of quality control when it comes to fit, wood and metal finishing, and metal hardening and tempering... but then their cost is higher as a result.
Over all, one's choice is a muzzleloading carbine aka musketoons falls between the P1861 type carbine/musketoons which is more or less just a docked Parker Hale or Italian clone P1853 4th Model rifle-musket.
And there is the rarer CS J.P. Murray carbine which is essentially a docked CS clone of the M1841 Rifle.
Enfield short arms such as the rifle and the carbine also fall under the same "de-farb" discussions as does the rifle-musket largely because the RM was based on P1853 4th Model RM primarily not used in the Civil War, and Parker Hale and the later the Italians basically just shortened it which creates other problems when compared to the originals.

Not a real Civil War reenactor, I only portray one on boards and fora.
I do not portray a Civil War soldier, I merely interpret one.
