Which magazine fits the Umarex Fusion 2 pellet rifle?

The genuine Umarex Fusion 2 .177 Caliber Pellet Gun Air Rifle Magazine is the only factory rotary clip built specifically for the Fusion 2 rifle. This black rotary magazine is engineered strictly for .177 caliber pellets and matches the exact dimensions of the rifle breech mechanism.

Using third-party or mismatched clips causes feed jams and bolt binding. Always check the packaging to verify that the rotary magazine explicitly states compatibility with the Fusion 2 pellet rifle before inserting it into your breech.

Can you use Umarex Gauntlet or Komplete magazines in the Umarex Fusion 2?

No, magazines from the Umarex Gauntlet or Umarex Komplete will not function in a Fusion 2. The Umarex Komplete 12-shot magazine is built exclusively for the Komplete NCR .177 caliber PCP air rifle (item number 2251556) with specific 1.5 by 0.5 by 1.5-inch casing dimensions. The Gauntlet rotary magazine is a 10-shot unit designed for .22 caliber PCP platforms.

Even though these rotary magazines share a similar shape, their dimensions and indexing teeth do not align with the Fusion 2 receiver. Forcing an incompatible clip into the rifle risks bending the internal indexing mechanism or damaging your bolt probe.

What part number identifies the authentic Umarex Fusion 2 magazine?

The authentic Umarex Fusion 2 magazine is identified by part number 2251366. It is cataloged under model number 2251366, UPC 723364513664, and EAN 0723364513664. The manufacturer lists the item weight at 0.03 pounds with exterior package dimensions of 5 inches high, 3 inches wide, and 0.5 inches long.

Checking for part number 2251366 is the fastest way to avoid generic rotary clips that fail to cycle smoothly. If a seller does not list this specific model number, verify the SKU with the retailer prior to purchase.

Can you shoot steel BBs from an Umarex Fusion 2 magazine?

No, the Umarex Fusion 2 magazine is engineered strictly for .177 caliber lead pellets. Steel BBs roll loose or jam inside the chambers because the rotary wheel lacks the magnetic or spring-tension retention required for round steel shot.

Loading steel BBs will damage the rifling inside the barrel and cause cycling failures at the bolt face. If you prefer shooting round steel ammunition for target practice, choose a dedicated CO2 BB gun such as the Walther PPS M2, which uses an 18-shot steel BB magazine (part number 2252413).

Will a Gamo Swarm Fusion magazine work in an Umarex Fusion 2?

No, Gamo Swarm Fusion magazines are completely incompatible with the Umarex Fusion 2. The Gamo Swarm Fusion G2 10X GEN2 Quick-Shot magazine (part number 621259054) is a .22 caliber clip designed for Gamo break-barrel autoloading systems and weighs 0.15 pounds.

The shared "Fusion" name causes frequent confusion in search filters, but Gamo and Umarex utilize entirely different magazine geometries. The Umarex Fusion 2 requires its dedicated .177 caliber rotary clip (part number 2251366) to seat flush inside the receiver track.

Why do airsoft and crossbow magazines appear in Fusion 2 search results?

Retail search algorithms frequently group broad shooting accessories together, mixing unrelated clips into pellet rifle feeds. Searches for multi-shot magazines often display items like the AR-7 Autoloader seven-shot crossbow magazine or the Umarex Elite Force HK G36 C 140-round airsoft magazine (part number 2275019).

Airsoft magazines feed 6mm plastic BBs and crossbow autoloaders handle bolts up to 6.7 inches long, meaning neither can interface with an air rifle breech. When outfitting your target setup or a tactical air rifle, double-check that the listing specifies .177 caliber pellet rifle compatibility to ensure seamless cycling.
