Looking for a good motion activated holographic type sight for a 10.5" AR SBR. Currently have a Holosun 510c on another AR and while I like it, I'm curious what else is out there that's similar. Really wish Eotech had this option. I do no want a tube style red dot, must be more the open window Eotech/holographic style. I've been looking, just hoping someone is aware of one I haven't found yet. Thanks.
