Just recently picked up the Kibler Colonial kit in 54 caliber. I am no where near the caliber of some of the builders I've seen here but I will say that this was a very easy project. I put together a Golden Age Arms kit 25 years ago, ahh pre-internet days. I was well out of my skill set on that kit but I got it together and have successfully taken deer.
For my 2nd 25th birthday I decided I wanted to treat myself so I started searching around looking at several companies and decided to go with the Kibler kit. Liked the way it looked, had some trepidation regarding the final fit (remembering my first kit) but once the kit arrived I was elated to find that all the hard (for me) work was done and final fit and finish was as easy as could be.
Chickened out on any carving and accouterments for now. Browned the barrel, lock and tarnished the brass. Pie plate accuracy at 50 yards for the first round of load development; just in time for late flintlock season in PA.
The pictures aren't great and the finish is a little wet in the picture.
PS my first kit arrived with a damaged stock (cracked forearm)- sad for me. Shipping of the kit from Kibler was outstanding. As secure as things can get, wooden box, barrel completely secured, wood completely secured and components safely tucked away.
