dboys metal body jg front set dont line up.
 

okay so i got a dboys metal 416 body to use with my jg416 the issue im having is two part. The frontset (ie the rail system) doesnt quite line up. The jg rail sits about 2mm higher then the top of the reciver.
Seccomd issue is the jg body has a tab that goes into the front set to hold the rail steady but the dboys body has the "proper" notch in the top of the reciver that the frontset is spose to slide into.
So my question i guess is. Does anyone know if there is a specific frontset that should mate properly with the dboys body (i guess a dboys front set lol) and will it work with the ring and barrel i have or do i need all the "fixins" to go with it.
And anyone know where to get it?.
Ill add some pics of what i mean shortly

No tab on rail notch on reciver

Also i notice both my mag brand mags and jg hicap seem to be really floppy in the magwell. Will the one peice type hop up help to hold em steady?

That body looks like my Gen 1 VFC 416. It's RIS has the tab.
