TM MP5 busted
 

Sorry for the post guys, was quite a bit younger at that time

The front end of the barrel falls off infront of you??? Or do the bb's roll out of the barrel?

Fucked up piston by the sounds of it (only by what happened to my G3-SG1 before)

Sounds like the hop up lever got shifted to zero hop up. BBs will roll out of the barrel then even when you don't shoot, and you won't get much range at all out of it when you do shoot.

idiot question

Send me some pictures of your hop up. And if you take it apart send some pics as well and I can give you some help. Do you hear an whining noise?

Your piston is invisible, no wonder it's causing you a lot of problems. ;)

Post a pic of your piston, let's see. Unless something is obviously broken on it, chances are it's fine.

My guess would be the tappet plate or the tappet spring broke causing the air nozzel to allow the bb's to roll thru freely. Or the little round piece of rubber fell out from underneth the hop up rubber also allowing the bb's to roll out the barrel as well!!

If the tappet plate broke, the spring would hold it full forward, preventing BBs from entering the barrel. And tappet springs don't break, *might* have slipped off the little post on the mechbox though, but it really wouldn't shoot at all, the tappet would stay full rear and BBs would just pour through the barrel no matter what.

I think it best for the original poster to clarify a lot of things for us before we continue to reply. His descriptions are extremely vague.

You are 13 and your brother forces you to do things at gunpoint? Why would we want to have this gun fixed? He does not sound responsible enough to me.

How old is he?

I think you should read the Newbie Guide, and the Information section about the laws related to airsoft, real soon.

Same for your brother.
