I tend to agree with @Art Caputo. The percussion locks were close to being acceptable, but it is a rare flint lock on one of the Jukar rifles that will be reliable. Some will spark when new, but the thin case hardening wears off. Springs are weak. In the 1970's these rifles really defined the flint locks are unreliable picture.
I have a CVA made in spain that will shoot 2" groups for me at 90 yds. A real shooter might just win a bunch of suff with it. Cant be a gun bigot, some are just plain awesme.
How's the bore? Questionable reliability or not, that is a pretty small amount of money for a flintlock based on what I've seen lately. Surely it's worth more than that in parts?
Lot's of dissing on the old CVA flintlocks. I can only relate my own experience. I built a CVA flintlock Kentucky pistol kit in 1974. Shot it for 10 years, still sparking the day I sold it. Never had any issues.
