## Description

Compatible with the Umarex AirJavelin Arrow Gun Air Rifle. CO2 NOT included.

Review: Essential Versatility: Umarex 2x12g CO2 Adapter for AirJavelin - The Umarex AirJavelin is a fantastic air archery gun, but it's typically powered by the larger, less common 88 gram CO2 cartridge. I purchased the Umarex 2x12g CO2 Adapter specifically to address this, wanting the flexibility to use the ubiquitous and easier-to-find 12 gram CO2 cartridges. This adapter is a must-have accessory that drastically improves the convenience of using the AirJavelin for target practice and shorter shooting sessions. Experience and Analysis The Umarex 2x12g adapter is a simple but brilliant piece of all-metal construction. It threads directly into the AirJavelin where the 88 gram cartridge would go, and it holds two standard 12 gram CO2 cartridges end-to-end. This is the core benefit: it allows you to utilize the incredibly common 12 gram cartridges, which can be found in nearly any sporting goods store, unlike the specialized 88 gram tanks. In practice, the adapter works flawlessly. While two 12 gram cartridges provide slightly less total CO2 than a single 88 gram tank (they are 24 grams total vs. 88 grams), the trade-off is well worth it for convenience. This setup is perfect for shorter shooting sessions where you only plan on taking a handful of shots. You can put in two fresh 12 gram cartridges, shoot for a bit, and not worry about wasting the remaining gas of a much larger, more expensive 88 gram cylinder. You get around 9 shots from the dual 12 gram setup, which is plenty for plinking or verifying your zero before a hunt. The adapter is robust and easy to install, making the switch effortless. Pros Convenience and Availability: Allows the use of common, inexpensive 12 gram CO2 cartridges instead of the harder-to-find 88 gram tanks. Prevents Waste: Perfect for short shooting sessions, as you don't have to worry about wasting the remainder of a large 88 gram cartridge when you're done. Solid Construction: Made from durable all-metal for a reliable seal and long-term use. Easy Installation: Simple screw-in replacement for the 88 gram cartridge. Cons Reduced Shot Count: Provides significantly fewer shots than the 88 gram cartridge it replaces, which may be a drawback for extended range time. Higher Cost Per Shot: Using 12 gram cartridges is typically more expensive per shot than buying in bulk with the 88 gram tanks. Verdict The Umarex 2x12g CO2 Adapter earns a solid 5-star rating because it’s a non-negotiable accessory for any Umarex AirJavelin owner who values convenience and accessibility. It solves the problem of 88 gram cartridge scarcity, making the AirJavelin a much more practical airgun to own and use. It's a fundamental piece of gear that pays for itself in flexibility and reduced wasted CO2. This is best for the recreational shooter or hunter who only takes a few shots at a time and wants to easily resupply their CO2.
Review: It fits Umarex Komplete ... Easy way to adapt to C02. - Installed this in my Umarex Komplete to convert to C02 ... No more expensive nitrogen cartridges. IT screws right in and works flawlessly. Point of aim at 10 meters was almost the same as with nitrogen ... very minor scope adjustment. Accuracy was same at 10 meters. The 2 -12g cartridges will give you 25 shots. If you buy the 12g cartridges in bulk, they will cost about 65 cents apiece. One nitrogen cartridge cost about 11 dollars and gives you 50 shots. 4 -12-gram cartridges will run you 2.60 and gives you the same 50 shots. Save the nitrogen for hunting. If your shooting paper or plinking use the CO2 adapter.
