Are ASG and SRC MP40 mags compatible?
I have been searching for the King arms 110rd mags for my Sten and they are sold out everywhere. I eventually located 110 rd SRC magazines and then SRC 280rd mags for the MP40. Can I use these?
pretty sure not as src mags only src , all others are fine just not src , you tried airsoft armoury as sure they showed in stock last week , or could ship some in from redwolf (hong kong) if they have in stock as 17% offf at mo
ah cool, hadn't tried them. They must have come after the 1st ten pages when I googled 'King arms mp40 magazines' 
Don't forget you can't use wind-up MP40 high caps in the Sten - because the mag is horizontal, the mechanism won't work properly (P90 hi caps are made to work horizontally).
