Button-rifled! Made for people who would like to restore accuracy to older guns with rusted, pitted or just worn out barrels. To install, first drill out existing rifling with a drill a little larger than the liner you are installing. For best results, we would recommend grinding or having someone grind a pilot on the drill about the size of the current rifling because this will keep it centered better , then solder the Barrel Liner in place. Or you can also use JB Weld or Acraglas gel because we have had many customers say they worked well.
