I finally got the money ready to buy myself a lage max 11 upper. I'm currently on the waiting list for a new batch to be made. Apparently though gone are the days of cheap plentiful Suomi drums. Can anyone speak to the quality of these grade 2 drums I see posted? Is the grade 2 just in appearance or is function going to be questionable? I suppose I don't mind a rustic look to be able to afford another magazine but I don't want to buy something that's going to be a headache.
