TM AUG feeding nozzle problem - need some help here

[GrieverX]

Hey everyone,

I was removing my mechbox from my TM AUG today, and the entire BB feeding nozzle bit came out loose with it. This is the part marked ST-20 from the Marui manual. I've been trying to figure out how to put it back in, but to no avail .

I seem to be able to put it back in the right place but then I can't get mags to lock in place with the ST-20 in there so I think I must have installed it incorrectly.

I'm just wondering if anyone knows how to install that piece back into the body?

Thanks guys.


Edit: Nevermind, figured out how to install it correctly now. Had to put it through some grooves at the side of the body.
Sorry for the noob question lol
