This Umarex 88 Gram CO2 Saver Adapter saves you CO2 because it lets you remove an 88/90 gram CO2 cartridge from an airgun without having the leftover CO2 leak out. The valve on the adapter closes when it's removed from a gun, so you can take it off and still have CO2 next time you want to use it.

Umarex 88 Gram CO2 Saver Adapter Features:

  • Black aluminum
  • For the Umarex AirJavelin, and 850 M2 (without cover)
  • Not compatible with the Umarex Fusion 2 Air Rifle

I bought this 88 gram CO2 cartridge adapter for the Umarex Fusion 2 air rifle. Don't buy it it does not work. I tried everything to get it to seat into the gun with no success, the cartridge is punctured, but gas will not leave adapter. I finally called Umarex and they say it doesn't work. So don't waste your time, money, and patience trying to return it to Airgun Depot because that will get you no where. They will send you a return authorization but you pay the cost of shipping. Dah! Thanks for nothing!!!!

Still don't recommend for the Fusion 2 unless you want to modify it

Update to previous review. Did as mentioned below and took off one row of threads and it works great. Can now use the 88g Co2 and remove it when I'm done shooting. Great device

If your buying this for a Fusion 2 just be aware it might not work for that gun at least not mine, but if you have a Umarex 850M2 works like a charm so happy with this adapter for at least this particular rifle.

This adapter works great for my umarex 850M2 it’s really nice to be able to fire a few rounds and store it for a later session of play.

It doesn’t work for my Umarex Fusion 2.

Not recommended for the Fusion 2 at this time

Good idea

Does not work on the Fusion 2 per Umarex service tech. They are working on the issue

Had to put on lathe and remove the first two threads do adapter could go in further to meet pin on gun

To the genius that left a 1 star, It says right In the description U ATTACH TO THE CO2. NOT THE GUN.

Obviously u don't have to use a Whole tank

doesn't work, fits co2 ok but the end is too short and doesn't make contact with pin on gun, waisted 2 co2 . emailed airgundepot with no solution

Cool idea something is wrong with it tho... maybe I got a lemon???

Doesn’t work can shoot at max 4-6 pellets then locks up and get no air. Took it out came home the next day put it in the gun and got two pellets out before it locked up. Screwed in a cylinder without adapter and no problems.

Will this fit the Sig Sauer Virtus?

asked Armando from USA

Would this thread to the Umarex Steel Strike? And if so, are there little valves where the standard 12g CO2 cartridges pierce that would make this not work? I'm thinking a little cheek pad on the tank and tons of fun. Or is there an alternative product?

asked Richard from USA

I’ve just purchased the Javelin. Bought two of the 2 pack non refillable 88 gram bottles. I want to test it out but don’t want to waste a whole bottle. Have you got the kinks out of the co2 saver adapter? I would like to purchase one if it works good. The reviews scare me. Have you guys been able to fix all the issues
