I’ve just attached a Noveske 10" hand guard to my Kublai M4, however I’m having fitment issues. It’s crooked when screwed all the way in - I assume the threads on the hand guard and the receiver don’t match up? I’ve also tried using the spacers that come with the hand guard and they don’t help.
My current fix at the moment is to attach my metal handle/rear sight across both rails to keep them together.
Has anyone had this issue before and if so, what was your fix?
