Lets "Too-Thin" Barrels Accept Win-Choke~-Style Tubes

If a barrel is too thin to tap for screw-in choke tubes or it’s chrome-lined (eats reamers/taps), or if the end has been bulged, you can install screw-in tubes. Simply turn the last ¾" of barrel to dimension in chart and solder adapter in place.
