I just got my Masada in, so I opened her up and noticed that none of my mags were feeding properly... so I looked inside, gave the feeder nozzle thingy (the part that goes into the mag to receive the BBs) a little flick, and it came right off. I've got a 450$ paperweight on my hands, don't I? As far as I know this part is proprietary, right? Even the barrel replacements don't have the lower half, afaik.
I've had a look at hop-up unit replacements for it; but I can only seem to find the upper half. correct me if I'm wrong:
(The gun was opened up once prior to change the spring)
Just in case, this isn't my first AEG.
