## Questions & Answers

**Q: Will this work in a vortex viper?**
A: it states the viper is a doctor,noblex footprint so it will fit just fine

**Q: Will this work for a holosun he507k-gr?**
A: 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

**Q: Does this come with any new screws/ bolts?**
A: 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.

### ⭐⭐⭐⭐ Fit and finish was great
*by J***E on August 20, 2023*

Installed it on my rifle and it looked great. But found out quickly my TRUGLO TRU-TEC 1X23MM 3 MOA MICRO RED DOT SIGHT, BLACK - TG8100B did not fit the holes that had been milled out in it for the buttons without modification. It can't fit everything and I'm sure every brand of red dot was not tested so I'm just informing buyers of my experience.
