I have an A2 rear sight with a fixed carry handle on my Bushmaster.  I noticed today that the sight base was loose ( I can move the sight base left and right) .  Is their a quick fix for this problem or should I send the upper back and have Bushmaster fix it?

It’s normal, don’t sweat it.

It's normal IF when you turn loose of it, it goes back to where it was. There's a ball bearing with a spring on the left side of the sight that should cause the sight to pivot CCW till it hits the carry handle.
