Differents RIS handguard for mp5sd

Edit 14/01/2024 :

It's been a long time since I put that model. So in order to make the MP5 SD6 better, I put all of the original designs files. Feel free to make some remixes !

Here, it is some handguard for a MP5 SD6. I use the 3 rails on my TGM Q6 from G&G, it works well. You can use the small black pins to stop the movement like the original. I have not a printer so a friend print for me i can not tell you the settings.
