Just ignore the wiggle. They all do it. It does not affect accuracy at all

[kiki]

It's fine, shoot more and worry less.

It will not hurt your rifle if you o-ring the front lug or drop a wedge in the rear lug.

A little movement between the upper and lower is normal.

If it bothers you, place a yellow EAR foam ear plug under the rear lug to take up the slack between the upper and lower receiver. Eventually, when the ear plug wears out, use the other ear plug.

Accuwedge the lower and o ring the forward ear. She'll be nice and tight.

O Ring works fine and doesn't stress the receivers.

Bad idea.

I came in here hoping the "m4 wiggle" was a new dance move.... Disappointed again.
