Will this work in a vortex viper?

it states the viper is a doctor,noblex footprint so it will fit just fine

Will this work for a holosun he507k-gr?

If it's a rmr pattern it should, you will just have to try& see ? You can always return it, I got it for a swampfox kingfisher & it fit the bottom holes but couldn't access the side power buttons, but a very well built mount, just have to try & see if it fits your sight. Good luck! Hope this helps! Capt J

Does this come with any new screws/ bolts?

Yes it does. But, I would only use the screws that came with optic, this way, you won’t void any warranty. I am very happy with this mount.
