Can I ask why?
For not much more weight and a lot more practicality, you could get a full-size scope (or even a compact, but regardless), and an offset microdot/Fastfire/Docter-type optic in the 1 o' clock position.
The magnifiers are just awkward. Big dot in the middle, extra lens, have to be especially certain it lines up correctly behind your optic.
FWIW, in all I have researched, I have not seen a reputable instructor using a magnifier -- but I'm sure some have and/or do, but... yeah.
