Also I found article on gunsholstersandgear.com
It breaks down a list of optics for hellcat.

I’m leaning toward the swampfox sentinel A (Auto) but every one has been sold out. Their website...
Also just came across this list of optics that will work with the hellcat with no mods and which ones require mods.

Hi there, I just ordered my hellcat and have been looking for an optic. I’ve seen the swampfox sentinel fits (on here and reddit). I’m really curious to see if the Burris FastFire 3 will fit. just ordered that guy for XDM Elite OSP. When I get the hellcat, and the optic I will let you know.
