I'm fairly certain the one I saw was a T12. The screen is only slightly larger than looking through an Aimpoint T-1. The thing is a piece of shit. If you are mounting it offset purely for spotting, you will be able to spot that there is a warm dot for you to watch out for. As for making out shapes, you'll have better luck reading the bottom row of an eye exam when you're old with bifocals.
Just look at this older model. Realise that the dude is only like 2 or 3 metres away, and see how small he already looks.
