CA MP5 SD front end - covert QD to threaded?
 

Currently I have a tracer unit with the QD adapter installed but I want to be able to go with a threaded flash hider or suppressor instead.

I saw this adapter on redwolf and need to know if it will do the trick?

Also, what does that grub screw secure? the adapter onto the front end?

grub screw question answered.

question still, will this adapter work on a CA SD QD?

Are the Marui QD's the same as the CA's?
