From what I've heard in these parts are the Sig optics aren't that great. I usually go with a Trijicon MRO or Aimpoint Pro on my guns but if I want good quality on a budget I would go with the Primary Arms 50k battery life red dot. Heard lots of good feedback from this 1. I plan to get 1 for my next rifle/pistol I get.

I don’t think it’s that sig optics suck, it’s that many are comparing apples to oranges. They’re like Vortex, they make everything from cheap shit I would only trust on a rimfire to legitimately duty-grade gear. Sig has a plethora of optics approved or currently in use with various LE and MIL organizations.
To address OP, there isn’t a best optic for the MCX, it depends on what you want. The Romeo 4M would be my pick if it needed to be tough and you want a red dot. If not, pick whatever looks coolest. If you want more range look at the Tango 6’s or Bravo 4 if going all out, or the Tango 4’s if trying to save some money.
