new mtc ret?

[Dan]

Can someone please help me , I've had trouble with my Mamba so the people at mtc have offered me a new evx when it comes out, they have to new rets MH10 (mil) or MOA10 (moa) I can not for the life of me find any info on these ,maybe I'm being stupid? So if anyone can find or has a picture of the new rets before I make a decision I would be very grateful .
