Glitch shooting glitch

I can guarantee you that this is lag. Do /ping once this happens and when it's not v: I'm sure you will see a difference! And does the chat also have a delay?

 

I don't know if yin can actually help with that because I remember him saying in shoutbox that it was the code or something, but feel free to prove me wrong because I probably am.

 

Maybe it's not lag. Since you are using Phanta's mod, there is a possibility that you are set on "Semi-Auto" mode which means you have to click each individual time you want to fire your weapon. Press F or look in your controls to see which mode you are in.
