I use a holosun 510c on my VR80. It has a circle dot reticle. Actually you can switch it between circle dot, dot only, or circle only. It’s solar powered, and or battery. Auto off / shake awake is also nice. Battery life is something crazy, like 50,000 hours.
I had a spitfire....... didn’t care for it. It always looked like more than 1x.
Holosun is a far better optic, in my opinion.
