## Description

desertcart.com: Monstrum Sentry Micro Red Dot Riser Mount | Absolute Co-Witness | Compatible with Venom/Viper/Fastfire/Docter Standard Red Dots : Sports & Outdoors

Review: Venom Picatinny Riser mount - Micro Red Dot Picatinny Riser Mount was easy to assemble and mount to my AR. The dust cover does not fit inside the riser to protect the Lense on the sight. Otherwise, everything fit perfect .
Review: Fit and finish was great - 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.

## Features

- For direct mounting of Docter/Noblex standard red dots to Picatinny mounting platforms
- Compatible with Venom/Viper, Fastfire 2/3, and all Docter/Noblex footprint pattern red dots. Please refer to compatibility chart before purchasing.

## 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.

### ⭐⭐⭐⭐⭐ Venom Picatinny Riser mount
*by R***5 on October 13, 2022*

Micro Red Dot Picatinny Riser Mount was easy to assemble and mount to my AR. The dust cover does not fit inside the riser to protect the Lense on the sight. Otherwise, everything fit perfect .

### ⭐⭐⭐⭐ 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.

### ⭐ Not for vipers
*by T***H on May 23, 2025*

This does NOT fit a vortex viper like it says. It comes with the screws and it looks like it should fit but the buttons on the side don't like up with the access area. Waste of time.
