It’s 30mm , I called their CS and they still told me 34mm despite me explaining that it’s 30mm. They dont know their stuff. I talked Dimitri (designer of this optic ) it’s indeed 30 mm . The Trybe enhancer only works on 30 mm tubes , wouldn’t make sense to sell a product that you can’t use with it . Optics planet CS sucks .

It says directly on the Primary Arms website that it is a 30mm tube.
