Just ordered one for my LEO Bushy.  Am I going to need a .040 front sight post for it to work properly and co-witness with my Aimpoint....Thanks...LL...

You won't know until you try it out. I had one carbine that didn't, the one I now have does.

My experience:  Had a A2 Bushmaster (16"), then when I decided I wanted a flat top, put a RRA A3 upper receiver on it with the same barrel.  When I put a ARMS 40A on it, I had to move the front sight post a whole two clicks to get it zeroed (25m BZO).

YMMV.
