Received Magnifier today. It all fit!
The ADM Red Dot mount lever and the Samson levers are pretty close together, but still easy to operate.
To get the Magpul MBUS thru bolt to fit in the rail, I had to sand just the mold lines off the front of the sight base.
I'm very happy with the Magnifier and mount. Both were very easy to adjust and use.
Samson mount with 7mm riser.
