Questions and answers

Will these fit my CO2 air pistol?
They are standard 12-gram cartridges, so they fit most CO2 airguns that take 12g capsules, including Umarex, Crosman and Daisy models. Check your gun's manual for the cartridge type before buying.
How many shots does one cartridge give?
It depends on the gun. A CO2 pistol typically gets 40 to 70 shots per cartridge, while a rifle may get more. Cold weather reduces the count.
Is $19.99 for 50 a good price?
That works out to about 40 cents each, which is a fair bulk price for branded cartridges. Generic 12g cartridges sometimes sell for less per unit.
Are these the same as Crosman 12g cartridges?
They are the same size and type, so they are interchangeable in most guns. Brand makes little difference to fit, though seal quality can vary.
Can I store unused cartridges?
Yes. Keep them dry and at room temperature; sealed cartridges hold their charge for years. Do not puncture or heat them.
What is in the box?
A single bulk box of 50 12-gram CO2 cartridges. No gun, magazine or accessories are included.
Where is the Umarex High-Grade 12g CO2 Cartridges for Pellet Guns, BB Guns and Airsoft Guns - 50 Count Bulk Box cheapest?
At Amazon, for $19.99, as of our latest check.
