I think I built about 14 Kibler longrifles all together, mostly the Colonial model. My last build was the Woodsrunner which I just couldn’t sell because I liked it so much.
The Southern Mountain Rifles (I built 2 or 3 of them) had the fastest ignition of nearly any flintlock I have shot.
The biggest challenge of any of these builds was fitting the butt plate on the SMR. That took hours in for me, (but I can work slow).
The locks are great and consistently highest functioning sparkers.
For any new builder these are the very best to kick-off with. You will get excellent parts, with near perfect fit out of the box, and will have a reliable, accurate high-quality flintlock from the get-go. You will also learn how a flintlock rifle is (should be) made and how the various parts are appropriately mounted.
Top it off with nice stock wood (no disappointments or surprises (save for better-than-expected wood), and a company that stands behind its product, it’s a great kit that’s enabled a lot of shooters with an affordable and high quality flintlock rifle.
(Maybe some day I will be building their Fowler as well.)
