This latest gun is just full of things I’ve never done today it was soldering on the lugs for a round barrel . I was dreading this as I was always terrible at soldering copper plumbing fittings. Have to say it went really well and super easy . I just tinned the lugs well set them in place on the barrel and heated the barrel from below with the propane torch the solder melted and lug settled right in place easy peasy ! Gotta say im probably done dovetailing any more lugs if it’s that easy . Once again thanks to all who posted info and knowledge so that people like me can learn and be successful .
