- I like them.
I got four of these and they work great. Shoots all but the last one with no miss feeding or jamming, fits nice in the gun, and it is much better than 55 rounds. Normally, I never buy a gun that I can't get at least a 200 round mag for, but I had to make an exception for this one.
My MP40 shoots 600 rpm with the recommended 8.4 battery. I usually run that, because my 9.6 would burn out the motor in a few games. So at 600 rpm these four mags actually last a while.
I do hope they eventually come out with something bigger though.
