I got an aimpoint ml3 and lt-150 mount combo as a gift today, and the aimpoint has a half moon shape on the the foward most piece of glass. It's almost like that lense has slid downward and I am looking through the edge of the glass if that makes sense. It looks like aimpoint put some sealer around the glass, but I figure that is done anyway, but I didn't know if all aimpoints showed this edge or not. If it's not a default, then it doesn't bother me, but I was just curious.
Thanks for your time.
