MP5 RIS handguard advice needed

[romain]

Hi guys!
I am planning to buy a MP5A5 AEG. First, I have to choose between those 3 vendors:
- ICS
- G&G
- VFC/Umarex

So:
- I tried an ICS and read several review and the general opinion is that it's a great replica. But a shop told me that several guys had an issue with some brand new ICS that broke their gearbox (a metal pin) and they have to change their entire gearbox. Also, this model it not so easy to find online...
- The latest G&G MP5A5 retractable seems cool and reviews seems to confirm that it's a robust and nice replica.
- VFC umarex seem also a good choice.

Now, My goal is to have a silencer and an RIS handguard.

I hate the one that come's with the G&G and want to replace it but can't find a compatible RIS handguard that cant fit on this model.
Same story for the VFC (also, I can't find it an adapter is needed to have a silencer on it...).


Please guys, help me! I have search where I could to find the right solution but you are my last hope!!!
Any advices will be greatly appreciated
Thanks!
