they have a 30 round low-cap 5 pack for 25 as well, but the same question needs asking. Will the plasticy mags work for me? Like, I need a few, and I know this. I'm a tad trigger happy. So Mid Caps would be nicer. That powered Drum Mag would be the best, but I didn't think most places would allow people to run around with 5000 round mags.
