If the Terminator was the type of cyborg to wear a ring then he probably would have selected the Cal Chamber Ring ($299). This stylish and unique finger band is perfect for gun lovers or those who light their cigar with a Molotov cocktail while it is most definitely a talking piece. The 44 Cal Pistol ring has been modeled off a real gun chamber while the stunning attention to detail makes this look the real deal. The Cal Chamber Ring measures 10mm in width and we think it is great.
