Which is better for a CO2 pistol or rifle?

Both are standard 12g cartridges and fit the same guns. The APS set gives you published pressure and purity figures; the Umarex box gives you the lower price.

Is the Umarex box worth the savings?

At $19.99 versus $29.99 at Amazon as of November 4, 2026, you save $10 on 50 cartridges. You give up the published spec sheet, not any known difference in fit.

Neither keeps longer by spec. Both are sealed 12g CO2 cartridges; store them dry and cool and use them before the seal or casing corrodes.

Does the APS set fit Umarex guns?

Yes. Both are 12g CO2 cartridges in the standard size used by most CO2 air pistols, rifles and airsoft guns.

Why is the Umarex box out of stock?

The listing shows it out of stock as of November 4, 2026. Check back or compare other 12g cartridge listings before you order.

How many cartridges do I get?

The APS set is 50 pieces. The Umarex title says 50 count, but its spec field says quantity 12, so confirm the count before buying.
