Thanks s0nspark! I mounted an extra RMR I had, but I just received the 'free' Vortex Venom' that was included in purchases thru Dec 31st. The Venom might be a better combo. Pretty good deal considering the gun is pre-milled and already has co-witness tritium sights set up. I really like the combo decocker/manual safety setup on this FN-FNX Tactical gun. You can run it SAO like a 1911 using the safety, or like a CZ/Sig DA/SA using the decocker only which returns to the 'fire' position. $1,075 all-in.
I wish CZ would produce an MOS ready set-up like several other brands.
However, now that I've figured out how to use IMGUR, I'll try to replace the dead Photobucket images in my old post of the $300 SP-01 optic set-up with J-Point that co-witnesses well without milling. (It's the bottom gun in 3 guns above). A lot of guys want to try an optic/co-witness set-up on their CZ-75's but don't want to mill their slide.
Thanks again for your tutorial on IMGUR. The key is re-sizing your image to 640 pixels wide so it doesn't go HUGE!
