When I bought a BCM rifle last year, I decided I wanted to put something other than one of the myriad of ~$130 red dots, but not an Aimpoint micro, and the MRO looked very attractive. Unfortunately, I found more “meh” reviews than anything. Frankly, I was pretty surprised considering Trijicon stuff is usually solid.
I ended up getting both a Vortex Sparc Solar and Holosun AEMS. I’m a big fan of micro style (20mm) red dots so the Sparc solar is a hit, no surprise. I wouldn’t pay $280 for it and am glad I got mine for under $200. At that price, I think it’s a solid deal for the quality and features.
The Holosun AEMS is really nice. The rectangular window offers much more FOV. I really feel like this is an underrated optic. Integrated flip covers, protective lens covers (both removable and replaceable btw!), selectable reticle, solar, and shake awake. That said, I don’t think the Core model is the value they intended it to be, I bought both, sold the Core.
