what cap are these? i may have to pick one up. if my ICS likes them, it tends to be a picky gun. . .
Try the King Arms first but if the King Arms mags don't work, let me know....
I have one brand new ICS M16/M4 high cap for $30.00. Bought 4 of them and they didn't work in the guns I had hoped they would.
Traded one to a friend, gave another away as a Christmas present, another friend has one that he tried in his G&G (didn't work!), and I have a brand new one in the package still. They are listed as 450 round but I suspect they hold closer to 400.
They work fine in the Dboys SCAR's but not in the JG, SRC, or G&G's. I suspect they would work fine in the ICS guns since they are ICS brand.
I will also sell the open one (tried on the field once) for $25.00 as soon as I get it back (probably at the 2/28 AIRDog game).
