I just received a new Action Army 50 round VSR10 mag. These are brand new on the market.
I tried it out and it is the first high capacity mag that I have had that has fed flawlessly without jamming and I was really impressed. It is a double stack like other high capacity mags but the Action Army 50rnd mags will actually feed properly as the spring is a higher tension than other springs. It also looks as though the bb's are stacked at less of an angle compared to other double stack mags. The steeper the angle that the bb's are stacked, the more likelihood that there will be a jam. So since the angle is less, the feeding is great. Also, often with other high capacity mags, the last 2-3 bb's will not feed at all as the spring does not have the strength to push the all the bb's out of the mag.
Another advantage with the mag is that it is see through. So you can see the amount off bb's that are in the mag when it is out of the rifle and you can also see if the mag needs cleaning.
