G&P have come out with a 10 piece set of their grippy Ball Ball Mid-Cap (130rds) Magazine w/Handle (FDE) for Tokyo Marui M16 Series. The handle is there for quicker and easy reloads. Hi Cap 340rnd magazines last a very long time during skirmishes which require less reload though you'll still have to deal with the winding at the bottom of the mag. Each magazine weights 140 grams as they're made out of plastic. Don't worry, you'll need it to be light if you're carrying 10 of these!
