As for the Pedersoli version of the Remington Rolling Block rifle, I've examined several new ones, and two weeks ago, looked closely at a used one about 5-8 years old.
The wood-to-metal fit and finish are very good, as is the bluing and color case hardening. I didn't care for the brass trigger guard, but that is how they come.
I've had a chance to examine authentic Remington Rolling Blocks from the late 1800's, and Pedersoli has done a credible job of making affordable quality rifles for the BPCR shooter.
I've not examined a John Bodine Edition, but expect that it will be at least as nice as the other tapered octagon barrel ones I've seen.
What would I look for and insist on is that your tang rear sight be windage adjustable, and the adjustments be crisp, positive, and snug. The biggest single complain among BPCR shooters with the repro Italian tang sights is that some lack repeatability and precision.
If you compare my previous comments on the Pedersoli M1873 Springfield Trapdoor rifle, you might wonder "WHY THE CHANGE IN OPINION??
The answer is simple: Look at the Rolling Block reciever and trigger guard, and you see all straight cuts, simple design, and few critical curves and fits. It can be duplicated easily on a CNC mill, something the 1873 Springfield can not.
