Got my spare upper for my Pre B back from my gunsmith this week.
He made me a custom Des Dot mount based on a picatinny rail with a backup sight included in den rail.
It is meant for a Docetr Sight (Red Dot) or basically any other scope that is mounted on a pica rail.
her some pics....and yes, it is kind of sick, but cool
