Issues - Fixing the wobble

Good news! The horrible wobble can be fixed! (Of course) There are a lot of ways to fix it but the one I did is with the use of an electrical tape. I cut small pieces of electrical tape and placed them on the surfaces where the two halves of upper receiver and the barrel assembly meets. This way, the electrical tape will fill-in the "gaps". Same theory when using a teflon tape on a loose threaded screw.

Also, make sure that the allen screw on the top rail is tight.

So far this is the simplest yet effective way that I know when it comes to fixing the wobble.
