Umarex 12g CO2 Adapter Set

  • Uses two 12-gram CO2 cartridges instead of 88-gram cartridges
  • Sturdy metal construction
  • Fits Umarex 850 M2, Walther Lever Action CO2 Rifle and more!

The Umarex 12g CO2 Adapter Set allows you to use two 12-gram CO2 cartridges instead of one 88-gram CO2 cartridge on compatible airguns. Using 12-gram cartridges prevents waste when only shooting a few shots, and they're easier to find than the larger 88-gram cartridges.

Things I liked:

Its a nice concept and its removable but you still lose some of the co2 by removing the unit from the weapon.

Things I would have changed:

Maybe a new two part design to eliminate the internal voids as much as physically possible.

What others should know:

12 gram and 90 tanks hold about 900 PSI, so Ive read. A 90 gram tank fires about 240 rounds + or - a few rounds at 70F. in my SIG MCX. Two 12 gram tanks give about 75 + or - a few shots in this rifle under the same conditions with the adapter. It takes 7.5 twelve gram tanks to equal one 90 gram tank. If you buy the 40 pack of 12 gram tanks for $25 thats .63 cents a tank. 7.5 twelve gram tanks is the equivalent of one 90 gram tank. Can not buy a half tank so, 8 twelve gram tanks is roughly the same as one 90 gram tank. .63 cents per tank times 8 is $5.04 One 90 gram tank is $7.50 if you buy the 24 bulk pack. Bottom line, using the 12 gram co2, the savings is $2.46 but swapping them out 4 times to get the same as one 90 gram tank. The adapter is currently $32.95 and would need to be used or refilled, at least 14 times to pay for itself in savings. Buy the way, this adapter does not fit in the MCX if you want to use the slide on stock that covers the tank. But it does without.
