• Twelve-capsule pack offers a portable supply for quick range visits
• Standard 12-gram footprint fits standard CO2 magazine and grip compartments

Which magazine fits the Umarex Zelos .22 caliber air rifle?

The factory Umarex Zelos high-capacity rotary magazine under part number 2251542 is the exact fit. This black rotary clip is built specifically for the Umarex Zelos .22 Caliber PCP Pellet Gun Air Rifle, which carries model number 2251541. If you configure your bench for a modern tactical air rifle, verifying that part number guarantees smooth cycling in the receiver without feeding issues.

How many pellets does the factory Umarex Zelos magazine hold?

The factory magazine holds 20 rounds of .22 caliber ammunition. Its high-capacity rotary setup provides more continuous shots between manual reloads, which keeps your shooting rhythm steady at the bench. The rotary design indexes cleanly so you spend range time shooting instead of repeatedly loading single chambers.

Does the Umarex Zelos use disposable CO2 cartridges or pre-charged pneumatic air?

The Umarex Zelos operates as a pre-charged pneumatic (PCP) pellet rifle rather than a CO2 airgun. While disposable 12-gram and 88-gram cylinders power a traditional CO2 BB gun, a PCP platform utilizes a dedicated high-pressure air reservoir. Confusing disposable gas cartridges with PCP air requirements leads to wasted supplies, so verify your filling apparatus supplies compressed breathing air rather than bottled CO2.

What specific rifle model number pairs with the Zelos 20-round magazine?

Model number 2251541 is the specific Umarex Zelos .22 caliber rifle model engineered for this rotary clip. Checking the manufacturer markings on your rifle breech or receiver for 2251541 confirms that part number 2251542 will insert and lock into place securely. Sticking to direct factory component numbers eliminates loose seating and chambering misalignment.

Can you thread 88-gram or 90-gram CO2 tanks onto the Umarex Zelos?

No, disposable 88-gram cartridges like part number 2252534 and 90-gram tanks like part number 40297 cannot power the Umarex Zelos. Those pre-filled cylinders are made for specific CO2 airguns or paintball gear requiring dedicated threading and adapters. The Zelos relies entirely on its onboard PCP air system, so disposable CO2 canisters will not connect or function on this platform.

How do you verify pellet compatibility with the Umarex Zelos magazine?

Verify that your ammunition is strictly .22 caliber pellets before filling the rotary wheel. The Zelos magazine model 2251542 is chambered exclusively for .22 caliber projectiles, meaning .177 pellets or larger hunting calibers will fail to cycle or seal. Checking the caliber listing on your pellet tin ensures every round seats flush within the 20-round rotary wheel for consistent indexing.
