Umarex Advice Regarding Umarex Hammerli AirMagnum 850 Adapter

[AirgunAmateur]

Hello.

I have been looking to purchase a adapter for the Umarex Hammerli 850 AirMagnum, the classic version, not the M2.
However I am confused on which adapter to buy.

When I look for the adapter, two appear, one which is
"Umarex Hammerli 850 AirMagnum CR20-S Co2 Convertor 2 x 12g Co2 465.101"
The other is "Walther Umarex Lever Action & Beretta CX4 Storm Co2 Adapter Set 88g to 2 x 12g"

To add to the confusion, I have seen two videos, one which shows using the first adapter I linked.
And another video showing it using the second adapter I linked, though this air rifle is a M2 I believe.

Also they both have different threads, one which has the typical 88g CO2 cylinder threads, the other looks like a half inch of threading only.
I did come across this image

which would suggest the first adapter, the black one, is the correct one.

Anyhow, any advice or reassurance would be great, I actually purchased the first one, then cancelled the order and began the process of confusion and doubt.

Thank you for reading.

Edit: Attached a picture of the CO2 port I have on the Hammerli.

the simple answer is both will work
the story was that the black tubed adapter lost less CO2 when you unscrewed it but who knows and it was the first one available and at the time they were about 100 bucks
now the price is way down i bought some from Umarex for less then 30 bucks
you can see in the picture they are the same size as a 90gr cart

Hey Marflow, I appreciate the response.

Put me at ease, I will look at reviews of both of the adapters now that I know I can use either.

Have a great day and thanks again.

i am not sure you are going to find the older style black one, oh sure there might be some around

I found the black one on the British Amazon.
I also seen them on eBay.

Amazon.co.uk

From looking at reviews I may purchase that, as the Walther/Umarex one apparently has issues depending on if you get unlucky in the build quality.

Just an FYI: eventually you are going to find 3 gram and 90 gram cartridges are expensive (about 10 cents a shot). Baker airguns use to sell an adapter so you could just screw in a bulk tank. My 3.5 Oz setup gets over 500 shots on a $5 fill, but it does add some weight to the gun.

I can give more details if interested.

Oh, and I love my Hammerli.

so, years ago i decided to make some single cart
they had the pieces on Ebay for less than 10 bucks and this was a time that the adapters were in the 100 buck range
i got some 1 inch ID 1.25 OD aluminum tubing and it was a little too big ID wise
i drink Safeway water and the plastic bottle was a perfect shim at 0.30mm and then took a single paper hole punch and Swiss cheese the plastic shim and epoxied together
you can see i made them the same length to the 88gr carts
i thought it would be a good tool for the short shoot and or testing for leaks
here is a picture of two complete and two others never done
the head will stay in the valve when removing, so i needed to remove that with a socket but no big deal
now this is just a show and tell as an idea
