Are these the same cartridge?

Both are Umarex 12g CO2 cartridges, so performance in a CO2 airgun or airsoft gun should be the same. The difference is the listing: pack count, price and stock.

B, at $19.99 at Amazon as of November 4, 2026, against $39.99 for A. B is listed as out of stock, so check availability before counting on that price.

How many cartridges do I get?

A is a 50-pack. B's title says 50 count, but its spec field says quantity 12, so confirm the count on the listing before ordering.

How many shots per cartridge?

A's listing states about 20 consistent shots per cartridge. B gives no shot count, but a 12g cartridge in the same gun should behave the same.

Neither. CO2 cartridges are sealed and used once; shelf life is long for both if kept dry and at room temperature.

Is B worth the wait if it is out of stock?

At $19.99 versus $39.99 for the same 12g Umarex cartridge, yes, if you can wait. If you need cartridges now, buy A.
