Has anyone have experience with the Aimpoint ACRO on a big bore? I have used Fastfires in past on shotguns for turkeys but interested in this for my 404J. Not sure I love the 3.5 MOA dot but I like it’s compact size and the idea it’s sealed unlike Fastfires and other red dot reflex sights. I have been thinking a Aimpoint H2 micro also. Thank you, Ed
