Are these pretty uncommon? I believe production was 2017-2020 from what I’ve read. I also read some posts describing difficulty getting replacement parts and wondering how big a potential issue this is? I see there’s an octagonal barrel 24” on GB now in 44-40 but I’m really hoping to find a 20” in 38 spc (or 45 Colt if they made that caliber).

Found one. I’ll report back on impressions when I get it. Thanks

I just took receipt of a Miroku Winchester 1866 Yellow boy in 38 spl. It is a 20” bbl short rifle with round barrel, plain walnut. This particular rifle is gently used as was advertised. Slicker than a miroku repro 92 that I have. Not sure if that’s due to the toggle design of the 66 or if this one has been worked on. It feels like it takes less force to cock.
The brass receiver is definitely heavier than the 92 and while I haven’t compared side by side the 66 feels a lot taller in the hand.
The fit and finish of these miroku levers are outstanding. I don’t however have a uberti or other clone to compare.
It should be a fun rifle to plink with and glad I bought it.

The Chaparral Arms 1866 is an interesting repo from a conglomerate Italian company that didn't last long. Quality reports are spotty. Mine appears to be near perfect fit and finish, and accuracy is excellent
