Like all of Mike's vids, I thought it was very well done. He even shows the mods he did with the cylinder and the load aperture.
I think he caters to many folks who are not stuck in the replica Colt world, as am I.
That said, I do not like the Rem NMA as it does not fit my hand like the Colt-style curvature. Just me.
Richard, if you want a project, design/configure a Remington NMA with the Colt 1860 Army grip style/dimensions, and you will make a fortune. You can call it a Colmington or a Reminolt, kind of like the Smythons of many years ago. ;-)
