A&K M60 feed tube out of place

[Terreus]

So, as some of you are aware, in addition to the feed tube from the magazine to the gun, there is a tube inside that brings bb's to the hopup. The tube inside the body has come loose and now there is no way to attach it to the magazine. I just got this in a trade so I'm not entirely sure how to disassemble it to get to the tube, so any tips help.

Thanks in advance, I'll try and post pictures of the problem later tonight when I have a chance to upload them

Behind the box is a nut you unscrew to remove the tube.

A picture would help

Yeah the nut came loose, I was actually able to fix it last night with a little bit of tool use and determination. Not sure how I'm going to keep it from happening again though...

i know the A&K m60 pretty well if you still need help...
