I'm shopping for Uzi mags for my 9mm upper.  I see there are different brands and different sizes (25, 32 and 40 rounders).

Are there any I should stay away from?

Are the 40 rounders as reliable as the 25 and 32 rounders?

Which ones do you prefer and why?

Does anyone have experience with the 70 round drums and what do you think?

Thanks,
Eric

Cant help you with the 40 rounders or Drum questions but.....Only buy uzi Contract mags...NEVER aftermarket!...Which is best for you? depends on which magblock you use...Some blocks are "tighter" and some looser,..Some "contract mags" are a little out of spec

is a good place to start,,,If the mags run well in uzi's and they're cut correctly then they will run well in AR's as well....UNDERDOG
