picking mid caps
i am about to place an order with a retailer and had a question regarding mid caps. After some reviews I have narrowed it down to King Arms 120 rd m4 box set or Mag 100 rnd m4 box set. The cost is close so that is not too big of an issue. When i spoke with the retailer they had told me that KA mid caps have had some problems feeding into VFC guns. And that I would be better off to go with MAG.
Just wanted to hear from you guys if you have tried the KA mags in a VFC body and how well or bad they performed.
