Technically Marine Recon are not issued ILBE system. It's a grunt thing. If you're going for MFR you should get EI Patrol Pack (Pantac has a version of it)
I'd also take off the PEQ15 as I've seen that maybe once in all the pics I've came across. Specter is the flavor of the year but ACOG would be good as well.
As for the rig itself, not too bad but I'd question the pouches layout... Are you a lefty? If not I'd move the MBITR to the left side. I know it's all AS but with a real MBTIR you'd have that whip antenna hampering a proper cheek wield of your gun. The centered frags strike me as odd as well, I'd personnaly move them to the side and consolidate the mags together.
But that's just me
I hope I don't sound too harsh or anything but I know you're looking at a "legit" looking kit
