Being a poor, I'm not privy to ZCO grade gear but I just bought an EOTech VuDu 5 X 25 for my 223 bolt gun. Good (not top tier) glass), lots of good features, and small. $1500-$2000 USD. Buy now, inflations's rampant.
Check Ebay maybe you can find an off shore vendor? Or get someone like Grateful Doug to do the paperwork for export? Or come for a visit and forget its in your bag when you head home.
Sure I wish I was not a poor and could afford a ZCO.
