So, im looking to form 1 a suppressor.

Ive only just had this idea about 3 hr ago and have never looked into this stuff before.

I really like the idea of a d6 maglite tube as a suppressor, plane and simple. So in Googling I've come across MMW and their adapters to run name brand qd systems. Has anyone used this system? Can i use an actual maglite body?  I do not want to run direct thread.

Yes, you can use an actual maglite body for a suppressor.  Some companies sold spacers and fillers and plugs to cover the hole where the clicky button was.  Then people started selling tubes that never were flashlights and never had that clicky button.
