Make sure you've got good gloves on when holding the STG in the cold, all that metal gets cold QUICK!
Mine so far has been fine. Have a KA drop in mechbox with a modify hopup and modify barrel in mine
With the mags being so big, the breadbag fills up quick and makes fair bit of noise with just 3 mags in it. If I have 4, I start to feel a little worried if one will fall out, but it does work.
I'll be getting my zelt soon, but I'll be giving it a dose of rain protector just to make sure.
Better safe then sorry
