Good idea aside, my experience thus far using several mag types including G&P mids, is that the only mag worth its salt is the Marui lowcap. Everything else is frustrating garbage. Maybe others like to turn their gun upside down, whack it, shake it, give it the magic blow to get it to shoot, but I'll forever be suspicious of any other mag.
So much depends on the mags in airsoft... cheap n cheerful doesn't cut it, flashing lights or not.
