As always when I experience something from use of a product I post up.  I was taking off the Trijicon MRO with OEM absolute co-witness mount off of my Aero Precision SBR and one of the hex heads decided it wanted to strip.  I have no idea why as the first one came out with no issues at all.  I decided to save the screw and dremel enough of a ditch to flat head it out.  I am going to try to re-use it until a mount comes out that I will migrate the MRO on to.  Possibly the new Geissele mount which I saw at SHOT.
