Ideal Use Cases

• Steel Challenge and NRL22 competitors who need a fast, no-fumble reload during or between strings
• USPSA and rimfire action shooters running courses that demand 20+ rounds per stage
• Casual range days where you want more rounds with fewer magazines
• Backpacking and field use where minimizing carried weight while maximizing capacity matters
• Any 10/22® shooter who wants a single, lighter alternative to running two factory magazines

Key Advantages Over Factory Magazines

• More capacity per reload: 20 rounds from one magazine versus 10, with no increase in seating complexity
• Faster second string: Eject, flip, reinsert versus tracking down and seating a separate magazine under time pressure
• Clear body for round-count visibility: Read remaining rounds at a glance
• Factory tuned out of the box: Assembled and optimized before it ships, no break-in or adjustment required
• Lighter combined carry weight: Two DoubleKross magazines equal four factory magazines in capacity, with less total mass
• Trusted reliability: Increased round count per DoubleKross Magazine still features 10-round rotary mag performance
• Reduced bulk: A DoubleKross Magazine loaded with 20 rounds is smaller and weighs less than a typical loaded 15-round extended magazine.

Limitations to Know Before You Buy

• Restricted states: Cannot ship to states with magazine capacity restrictions including California, Colorado, Connecticut, Delaware, District of Columbia, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island, Vermont, or Washington
• Capacity per compartment is 10 rounds; each side functions as its own 10-round rotary magazine
• TANDEMKROSS guarantees compatibility with factory Ruger® models in factory furniture and TANDEMKROSS original firearms. Results with third-party chassis or receivers may vary.

Is the DoubleKross Magazine legal for competition?

Legality depends on your sanctioning body and shooting class. Each compartment holds 10 rounds, matching the standard factory magazine count, so the DoubleKross is generally legal in classes that permit 10-round magazines. Steel Challenge and most NRL22 rulebooks do not restrict round count per magazine during most stages; verify current rules with your local match director before competing. The magazine is a coupled 10-round design, not a high-capacity magazine under most federal definitions, but check your state laws. The DoubleKross cannot ship to several states.

Does the DoubleKross Magazine fit my 10/22® without modifications?

Yes, for all listed compatible models: Ruger® 10/22® Carbine, Takedown, Takedown LITE, Compact, Tactical, Sporter, Target, 22 Charger™, and the TKX22 Light Rifle. The DoubleKross uses the same rotary magazine footprint as the factory 10-round magazine and seats in the same receiver. No modifications to the firearm are needed. If you are running an aftermarket chassis or stock with a non-standard magazine well, verify clearance before purchase.

How do I reload with the DoubleKross Magazine?

After your first 10 rounds, drop the magazine, rotate it 180 degrees so the second compartment faces forward, and reinsert. This flip-reload is faster than seating a separate magazine because the motion is consistent and the magazine stays in your hand throughout. Load both compartments before your stage and you have 20 rounds ready across two identical insertions.

What is the difference between the Assembled DoubleKross and the DoubleKross Magazine Body?

The Assembled DoubleKross Magazine includes the complete, tuned magazine ready to load and shoot, with all internal components installed and optimized at the factory. The DoubleKross Magazine Body is the housing only, sold separately for shooters who want to build or rebuild their own magazines using parts they already have. If you want a drop-in, ready-to-run magazine, choose the assembled version. If you are replacing a damaged body or building a custom setup, the body alone is the right choice for you.

IMPORTANT: Cannot ship to California, Colorado, Connecticut, Delaware, District of Columbia, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island, Vermont, Virginia, or Washington.
