The 8 simple tools you need to start gunsmithing at home

#4  HAMMERS

Hammers give your punch the extra encouragement needed to drive pins and move sights. Use an eight-ounce ball-peen hammer, but keep a 12-ounce ball-peen on hand for stubborn pins (anything heavier than 12 ounces can cause more harm than good). For added protection or when trying to move stuck parts, use a rubber, nylon or brass hammer to avoid marring the firearm.
