Things I liked: This CO2 adapter is a great addition to my Hammerli 850. The larger 88-90 gram CO2 tanks are very difficult to find in my area. I really like the ability to use 12 gram CO2 cartridges and be able to remove the adapter without loosing all the CO2 in the cylinder.

Things I would have changed: A little expensive but worth it to me.

What others should know: I have to use a penny between the 12 gram cylinders or else one will not get punctured when installed.

Things I liked: I like the versatility this adapter gives me. If I don't have enough time to consume an 88 g CO2, I can use this adapter with 2 12 g CO2. I get about 80 shots per two 12 g CO2 which is just enough for about an hour to an hour and a half of shooting.

Things I would have changed: Nothing

What others should know: I've successfully used this adapter with Crosman 12 g powerlets without having to use the penny that others have recommended using. Unfortunately this adapter is an inch and half too long to be used in the Walther Lever Action rifle. When installed in the Walther rifle stock, the stock cover can't be reattached.

Things I liked: The adapter works very well. So far no issues. A must accessory for the Hammerli 850.

Things I would have changed: A little pricey

What others should know: I read of people having some problems with there not being enough tension between the 2 12gram co2 cartridges. One fellow said he solved it by placing a penny in between them. I did this right off the bat.

  • Steven from USA asked:

    can someone please tell me the length? Is it longer than a normal 88 gram cartridge?

    • Jonathan from USA asked:

      Will this fit the Crosman Night Staker?

      • Richard from USA asked:

        Will this fit and work with the Beretta CX-4 Storm with the butt stock cap removed?
