Just purchased and it comes with low and full co-witness bases but I want it to be 1/3 co-witness. I can't find a specific base to do that. Does anyone know where I could find a 10mm picatinny riser? I have found numerous .5 inch (which I think is slightly to high) but nothing in mils. I want to use it with an EOTech magnifier I already have. Thanks in advance.
