Excellent protection for your optic
The Monstrum Sentry Optic Riser Mount offers great protection for my Holosun 507c Optic. It’s quality made and appears to be truly rugged. Offer true co-witness with flip up sights. Installation is easy and comes with multiple length screws and the installation tools. Highly recommended.

A++ Excellent Mount—Solid and Reliable!
This Monstrum Sentry Micro Red Dot Riser Mount is great! It provides an absolute co-witness setup and is rock-solid once mounted. The build quality is excellent, with no wobble or movement even after extended use. 1500 rounds through it so far and no wiggle. It holds my red dot perfectly aligned and makes target acquisition quick and easy. Installation was straightforward, and it fits snugly on my rail system. If you're looking for a durable and reliable riser mount, this one is a top choice. Highly recommended!

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.

Not for vipers
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.

Solid - Works as Intended
Perfect fit for the Swampfox Justice. Access to the optics controls is a little less convenient, but I say it's a fair trade-off for the extra protection. The box contained the correct screws and everything I needed, except for thread lock. I hadn't had it installed for more than an hour before it protected my optic from a pretty hard knock. I'm happy with it.
