Built one several years ago, my second Chambers kit. The thin round barrel means soldering the lugs and front sight, and you're aligning them on a round surface, not a nice barrel flat. As others advise, go slow. The gun is great to carry - light and well balanced. I don't shoot a ball well yet, as I am addicted to rear sights, but I think once I get my sight picture in my head it will be a fast shooter. I have been able to break clay birds with it. Note that the website pictures don't do the gun justice. It is truly graceful and elegant.
