This is a pretty good magnifier, but there is a few problems the magnifier. I am using the the Holosight from b-2 also and the dot and ring does not come out to clear when your looking threw the magnifier. The mount that it comes with is very cool. But a little tiny screw fell out of mine and now it sits all wrong. The spring on the mount seems to be a little to powerful. It will man handle Magnifier witch is why i think the screw fell out.
Is a square Magnifier instead on a circle
QD is pretty nice
Not sure if it all is metal, it has a rubberlike coding on it
it has some weight to it
You cant put the Magnifier on RIS you have to have the mount
