Is there enough room to have all three on a S&W M&P 15T? If there is, can you mount the Eotech on the top rail and have the magnifier on a "flip to the side" mount? Or would you have to mount the magnifier straight on the rail too, if you want things to line up correctly?
If you have some pictures of this set up I would really like to see them and if you have some suggestions for a magnifier I would like to hear them too.
