I am looking to mount this setup...

Just an EOTech 557 with 3x magnifier behind it. Can I still put a BUIS behind the magnifier or does it move the magnifier to far forward for proper eye relief.
And will a Larue QR mount work with the EO and Mafnifier?

1. It will fit as long as your 557 doesn't bump your handguards. It will bridge the receiver and the handguard a bit.  Do you have freefloating handguards or the MagPul MOEs? That will make it an easier fit rather than the fat M4 handguards.
2. LaRue makes a specific mount for the EOTech magnifier so make sure you get the right one.

I have a free float handguard. S&W M&P 15 with quadrail.

So eye relief will be ok with the BUIS and Magnifier??

The 4X worked for me and it has the shortest eye relief at ~1.6", roughly the same as the ACOG 4X series. You will notice it so shoot NTCH, for sure.

The 557 sits 7mm higher than the typical EOTechs, so you'll probably need a tall magnifier mount to properly align the magnifier and the EO.

I used one of the Larue TALL flip to the side mounts with EOTech 553 and an Aimpoint magnifier and it sits perfectly on top of my MAGPUL MBUS.
