Traditions guns like CVA, are made is Spain by Jukar Company. The quality is good but not the quality of Thompson Center or Lyman. You can always tell about the quality of a gun by how much dollar value is retained when it comes time to sell. Folks just aren't interested much in used Spanish guns.
I sincerely believe you will be disappointed by the lock. The quality is low-grade. In this business like others, "you get what you pay for (new), AND you pay for what you get".
I know you said it before, but you will be miles ahead if you spend your hard-earned money on a new (or used) Lyman flintlock Great Plains rifle in .50 or .54 caliber. They sell new for about $600, I sell used ones that are twenty years old for $400 to $450.00. That's a measure of quality and performance.
I'll buy any Lyman Great Plains rifle in like-new condition in a heartbeat, but I'll pass on ANY Traditions/CVA rifle, except the CVA Mtn Rifle made in USA.
'Nuff said."
