Verified Purchase

Things I liked: Ability to use the more economical 12 g CO2 cartridges either single or double (One live and one used cartridge) for various shooting situations. Very high quality engineering is evident. A very solid, sealed cylinder. Being able to remove the adapter with the 12 g cartridge (-s) sealed inside is terrific. You simply can't remove a partially used CO2 cartridge from your pistol or other single CO2 cartridge airguns. For frequent practice, it's perfect. For longer sessions or friendly contests, go with the 88-90 g cartridges at $7-8 a pop. (Pun intended)

Things I would have changed: Functionally, nothing. Well conceived complement to the Hammerli 850 Magnum

What others should know: While the initial purchase price of $100 will likely dissuade many from purchasing this adapter, with time, it will pay for itself. This adapter actually encourages the user to practice frequently instead of episodically as an inexpensive CO2 cartridge is all that is consumed. If you think that the 88-90 g cartridge is still the way to go, try to get the full 200+ shots out of one. The pressure starts dropping off well before that and your accuracy suffers tremendously. "Bite the bullet" and buy the adapter! (Disclaimer: I don't get any commission for any sales.)

Things I liked: The ability to shoot around 65 shots per session.

Things I would have changed: Lower the price a little.

What others should know: I've read about people using a penny to separate the powerletts, I tried without and have no problems. Puncture both fine, lasted 2 and a half days. More of a convenience that a necessity.

    Can it be shipped to Brazil?

      Will I loose a lot of power by using this adapter instead of 90 gram C02?

      • Stanley from USA:

        No more than likely it will get fewer shots .

      Does this work for the walther lever action co2 pellet gun?
