Ultimate Battle Megatron Woes

Does anybody else's Megs have severe problems with the turret arm?
The canon arm is incredibly loose at the point where it connects to the hexagonal peg, so the Gun arm is always falling off. If I try to use the spinning gimmick it'll just fly off.
The rest of him is pretty solid, but that arm just gets to me. Anybody have a fix for that?
I do however like the nod to G2 Hero Megs he's got going there. Even his gun resembles that of G2 Megs.
