Go to any Xbox Server where PVP is common and im sure you will see someone complain about it;
First you run up into a fight and bam there it is your gun doesn't do anything to the guy you're shooting but guess what your moving just as fine on their screen as you are yours.
Mag dump? yeah you better be lucky the other guy is trash at the game because the only way you will have working hitreg is if you survive for ATLEAST 5 seconds after your last shot.
I am not the only one with this issue i can link you to a Discord Server full of people who play on the same server as me who have this issue and it's stupid common - there are no server/connection icons just pure bad net code.
Attached is one example of this issue.
