A friend posted a pick of the 30MM and it started a discussion. I bought the 20mm which is impressive but the 50cal make a great gift (they add engraving and such) and it's literally the best bottle opener I've ever owned.
Great gift for the gun nut with everything .. or at least a bottle cold one.
My son bought me a blue one with the EMS star of life and my name on it for Christmas a few years ago. They are awesome. If it wasn’t boxed up while I’m moving I would snap a pic for everyone.
