Welcome to the Club Bohica!
I can't wait for my upper to arrive! I plan to mount my 4X ACOG on mine. Then, I'll take it to the field and verify the exact yardages of impact for the ACOGs trajectory markings. Since I plan to keep my Bohica .50 BMG around purely for SHTF scenarios that are 99.99999999999% improbable, I don't plan to put a big, dedicated scope on it. I won't be using it for regular target shooting, etc. That would merit a good scope.
In closing, can you believe the price on these uppers?! $995.00?! Lordy sakes alive...300 rounds of ammo costs more than the upper.
