worked well
this has more than paid for itself in cartridge savings,you but bulk cartridges st a fraction of the cost bbn of the larger ones,also good if you are not going to be shooting that many rounds,worth it

I really like this adapter, It is great for when I don't want to use the 88 gram co2. plus I can take it out of the gun without having to leave the gun fully charged which will put pressure on seals and use it again.
ProsLets one use two 12 gram co2's and one can take it out of gun
ConsNot much I put a penny between the two cartr. for a tighter seal that's all a great accec.
Best UsesReplaces the larger and more expensive 88 gram co2 and you can put it back in again instead of having to keep it in gun or shoot it out.

This works great, added a little oil to the treads to make the cap tread easier hold co2 so if you do not want to shoot tell empty just remove from my air gun and come back another day, great.

Hammerli 850 12 gram CO2 Adapter
I have had several different air rifles in my time. I love this rifle, it is extremely accurate and well made. If you are looking for a CO2 rifle then look no further. You will not get another rifle in thes class for under $300.00.
ProsI love this rifle, it is extremely accurate.
ConsThe only thing I would change is the safety to metal instead of plastic.

Best Hammerli Accessory
This is a top quality item and a 'must' if you are going to do a lot of shooting with your Hammerli 850. I've had mine for over a year, and it has been flawless -- both the rifle and this adapter. It was a tough call, spending another $100, but it has already paid for itself. It is easy to use and a couple of other reviewers have pointed out it's best to drop a penny in between the two cartridges for positive engagement of both. The adaptor may also be removed from the rifle without shooting out all the air. Good stuff. Treat yourself, get one of these.
ProsSaves money in the long run; easy to use.
ConsPrice. They would sell four times as many if the price was $50-60.

12 gm adaptor
I don't shot a lot so using an 88 gm CO2 cylinder means storing the gun with the active cylinder and risking possible seal damage. The 12 gm adaptor can be removed without losing CO2 and risking seal damage. This is a superb offering.
ProsCO2 flexibility

Good Back Up
I've used this once just to see how it works. I ended up getting many more good shots out of it than predicted. I believe it was close to 80. It drops off very quickly though and I ended up leaving a round in the barrel because there wasn't enough power left to shoot the gun. So, really stop and change cartridges at the first sign up power going down. It was very easy to install. Just be sure to screw it in all the way. First time I thought I had it in all the way and the gun wouldn't shoot. Took it out and screwed it in again and found there was still another 3/4 turn left. Then things were fine. I wouldn't recommend it, not because it's not a good product. It's actually made very well and works even better than advertised. It's just that you can shoot the 850 quite cheaply on 88gr CO2. Check out The 850 Store for details on how. This product is marketed as a back up to the 88gr CO2 bottles, and it's just not necessary.
ProsMade very well. No cheap materials Easy to use More shots than is advertised (of course, depends on temp.)
ConsNot cheap!

`You get what you pay for. The price is high but you can unscrew the adapter from the rifle (Hammerli 850) and the CO2 is still in the adapter!!! This is a great way to use 2 CO2 powerlets. Use a penny between the powerlets (Crosman) to puncture both but if you don't you still get the same power but for less shots. That is how CO2 works. It is truly worth the money as a 90 gram cylinder costs around $6.50 at Walmart. That is 7.5 12 gram powerlets or $3.75. (40 powerlets for $19.95 is the best deal I see anywhere). 42% price break 90gm vs 12 gm !!! Actually 49.875 cents per powerlet but who's counting :) Every 7.5 powerlets would give you $3.75 savings per fill so after 198 powerlets or $200 bucks the adapter pays for itself (It is free after 200 powerlets) !!!! In 3 months I have used 80 powerlets so get the adapter!!!! Or use 30.46 x 90gm cylinders and incur no savings period. 6000 rounds goes fast if you love this hobby like I do!!!!!
ProsFine engineering, cost savings, ability to "unload" without wasting entire CO2 powerlets. I don't think there is an "O" ring here only like a quick coupler type situation but I could be wrong on this. This adapter is quality built like a tank in Germany.

I got a co2 air gun, an Extreme co2 Gamo. Doe's this adapter work on my gun, because it is a cause of frustration to waste the expensive 88 gr co2 cartridge when you shot just a few shots and you must remove the cartidge to avoid damaging your gun?
Thank you for answer.
Best regards, Constant O.

It can work with many guns that would use the .88 gram Co2 canisters, though it does not fit all guns.
