M&P Sport Rail Question, need help guys

[Nole93Nole99]

I was wondering the rail length on the M&P Sport, if anybody has one and can measure it for me I would really appreciate it. Thanks for any help

Basically the top rail, in the pictures it looks to be 5-6 inches. Im looking to put a Eotech 552 A.65 Sight and also the Eotech G23 Magnifier on it and I want to make sure ill have enough rail space or if ill need some sort of extension rail. Thanks for any help or suggestions.

The top rail on mine is 4.25" long. I added a Mag pull rail ($6.95) to the bottom of my forearm for a light, it could also be put on the top or you could swap the forearm for a quad rail type if you want to add a lot of stuff to it.
