Best red dot sight for HellCat Pro

[Popop]

I plan to purchase a HellCat Pro and want to know which is the best red dot sight to purchase and install.

I think the Shield RMSc or the Holosun 407k would be the ones to look at. Their performance and quality is proven.

If the depth of the optics cut on the pro is the same as my regular hellcat OSP, then a holosun 507k is too thick to see much of the stock sights, especially if you decide to use an adapter plate. It appears the RMSc is thin enough to allow you to see a much larger portion of the stock sights.
