will a wobble between upper/lower cause accuracy problems?
No.
Not so fast. The US Army looked at the issue and said based on the fact the iron sights were on the upper, the accuracy
SHOULDNT be affected. Once you mount an optic that
SHOULDNT gets changed to a
MAY, and when you add a magnified optic that
MAY changes to a
LIKELY. The recoil caused the sight pictire in the optic to move off center from where you were before, so you would gain a slight paralax after each shot.
But all in all...No, accuracy isnt affected to the extent you will see it. Its about the same as a FF vs a 2pc HG set up. Very few will see an accuracy increase with a FF.
I stay away from the accuwedge since it will degrade over time and may jam the FCG. When I found this wobble on an well used A2, I used a small piece of plastic and sandwiched it between the upper and lower forcing an upward pressure. I have seen other guys use tape to build up the inside edges of the lower doing the same thing.
