The brand "Redwin" sells on Amazon for lower prices than Vector Optics, but they appear to be out of stock right now. Will try to update this if I see them in stock.
Since I made this video, I found out about the Gideon Omega, which also looks like a good SRO clone. I do not have one right now, but might get one.
