As for why the mags take longer to reload, you need to charge the mag with propane or green gas and fill it as opposed to just filling it with bbs in the standard AEG mag.
Oh, well, no I knew you had to charge them with propane, I thought he meant that on the field, with multiple mags, it took longer to put one in the gun, charge a round and start firing.
