I have a 9MM Oly upper, and am interested in getting a Oly .45 upper.
Okay, the mags that come with the Oly .45 are UZI mags with a welded on block. I have looked around various places and can't find UZI .45 mags larger than 20 rounds, and most are $15 or higher. A big difference than getting 9MM Sten mags for $4 in bulk.
What other .45 mags can be used with mag blocks and such? I know that grease gun mags are too wide for standard AR lowers.
What about thompson mags?
Thanks in advance,
