Getting Started with the Umarex CO2 Adapter
The Umarex CO2 Adapter offers a convenient solution for airgun enthusiasts seeking an alternative to the larger 88 gram CO2 tanks. Specifically designed for compatibility with airguns like the Umarex AirJavelin and 850 AirMagnum, this adapter allows users to utilize two readily available 12 gram CO2 cartridges. This innovative product promises flexibility and potentially lower running costs, making it a worthwhile consideration for those heavily invested in CO2 powered air rifles.
I was drawn to the Umarex CO2 Adapter out of frustration with the limited availability and higher cost of 88 gram CO2 tanks. Sourcing them locally often proved difficult, and online orders added shipping expenses and waiting time. The promise of using readily available 12 gram cartridges, found in most sporting goods stores, offered a welcome solution.
Upon unboxing the adapter, my initial impression was positive. The adapter has a solid feel, exhibiting a robust build that suggests it can withstand regular use. The silver finish gives it a clean, professional look.
Compared to simply sticking with 88 gram tanks, which is the obvious alternative, or attempting to rig up a custom solution (something I wouldn’t recommend for safety reasons), the Umarex CO2 Adapter stood out as a purpose-built, safer alternative. It seemed better than potentially unreliable aftermarket solutions. I chose it for its simplicity and Umarex‘s reputation for quality.
My first impression was one of cautious optimism. I was eager to see if it would live up to its promise of providing a reliable and cost-effective alternative to 88 gram tanks. I was also hoping it wouldn’t drastically affect the performance of my Umarex AirJavelin.
Real-World Testing: Putting Umarex CO2 Adapter to the Test
First Use Experience
My initial testing of the Umarex CO2 Adapter took place at my backyard shooting range. I used it with my Umarex AirJavelin to target practice at distances between 20 and 40 yards. I wanted to see if it could provide consistent power and accuracy compared to the larger 88 gram tanks I was used to.
During the testing session, the weather was mild and dry. Under these optimal conditions, the adapter performed admirably. It was simple to install, and swapping out the two 12 gram cartridges was straightforward.
The adapter was easy to use straight out of the box. Installation required no tools and was completed in under a minute. I just needed to ensure the 12 gram cartridges were properly pierced and tightened.
My first-time use revealed no significant issues. However, I did notice a slightly lower shot count compared to a fully charged 88 gram tank. I also observed a very slight decrease in power towards the end of the two 12 gram cartridges.
Extended Use & Reliability
After several weeks of consistent use, the Umarex CO2 Adapter has proven to be a reliable piece of kit. I’ve used it in a variety of temperature conditions, from cool mornings to warm afternoons, and it has consistently performed well.
The adapter has shown no signs of wear and tear, despite being frequently handled and used. The metal construction appears to be durable and resistant to corrosion. It has been cleaned after each use with a dry cloth, as recommended.
Maintenance is straightforward: simply wiping it down after use is generally sufficient. I occasionally lubricate the threads with a small amount of silicone oil to ensure smooth operation. Compared to the hassle of sourcing 88 gram tanks, this adapter has been a significant improvement. The cost savings alone have been quite noticeable.

Performance & Functionality
The Umarex CO2 Adapter performs its primary function effectively: allowing the use of 12 gram CO2 cartridges in place of 88 gram tanks. Accuracy remains consistent compared to using the larger tanks, although shot count is reduced.
The main strength is the convenience of using readily available 12 gram cartridges. The primary weakness is the reduced shot count and a slight drop in power as the cartridges near depletion. It meets expectations for convenience, but falls slightly short on overall power and longevity compared to 88 gram tanks.

It’s easy to install and use. There is virtually no learning curve.

A quick wipe-down after use is typically all that’s required.
Accessories and Customization Options
The Umarex CO2 Adapter doesn’t come with any additional accessories. It’s a standalone product designed to adapt existing airguns to use different CO2 cartridges.
There are no specific customization options available for the adapter itself. However, it allows you to continue using any existing accessories for your compatible Umarex airgun, such as scopes or bipods.

Who Should Buy Umarex CO2 Adapter?
