Robby, do the Emags actually feed better? I know they do for real guns but what about airsoft?
they feed great so far, haven't fielded it yet, but i will guess it's just as good as my PTS PMAG which has fed every time although the design is slightly different (see pic below of top view, hard to tell from pic sorry) but this could also be an earlier generation PMAG that I have.
And do you know how much slimmer than regular pmags they are?
They are the same width as the PMAG, which is honestly the same width as a MAG M16 mag (bad angle in the pic, but they are the same), the only part being thicker is the base plate. The major difference is the angle of the mag and the cut in the front of the mag to accommodate mag wells that are not AR-15 spec (see pic).
