Been shooting it like this for a while now and no issues, read somewhere that this is not a good idea. Wanted to check here.

YES this is very bad. Move it back.
When you pull the trigger the barrel and rail are going to flex a bit. By bridging the gap you are putting stress on the mount, the upper and the rail ever time you fire a round.
