https://www.brownells.com/optics-mo...s/retro-4x-carry-handle-scope-prod124965.aspx Japan Optics Co (formerly Hakko Japan) has cataloged this scope for years but there was a minimum (of 50 I think) order to import them. Fully warranted, not made in China. My XM needs this optic. I have a Hakko 'blue ring' elctro dot scope on my Colt 6920 that I was considering moving over to my XM build. Looks like this is going to be on the market soon!
