Hi guys! So yeah, the problem is the one i mentioned in the title. There's a way to fix this issue? How can i place the sub-ar in order to make it not-free spinning? Please, don't tell me to use some super glue 

It can't be fixed in a position, that's just how it is. S-ARs are designed and supposed to spin freely.
It doesn't hinder Dark Wing's performance for smash attack though.
