No RJ it is not you. I would bet you a 9.99 taco plate lunch that it is bigger than either the Holosun or the Acro.
As both those dimensions are widely available, one could have measured the SF offering if one was so inclined to make such a comparison.
I freely acknowledge that I am making a WAG based more on human nature re sales/marketing etc. than anything more scientific like trying to figure out high the rear sight or some other dimension on the gun is and extrapolating from there.
As per a chat with SF today, it, like all SF red dot optics are made in China.
