Seven years ago, I built a .45 cal. Pedersoli kit sold by Dixie as their Cub Scout model, for my grandson's 12th birthday. It turned out to be a shooter. He outgrew it a couple of years ago, and now has a grownup, full-sized longrifle in .50 cal.
The lock on the Pedersoli kit was a step down from a Siler, but never gave any problems, and is still a sparker.
Good luck in your search.
