Frequently Asked Questions

How do I test the tension of my Ruger 10/22 or 77/22 rotary magazine?

To test the tension, load one dummy round into the magazine. Press against the cartridge case; if it snaps back into position when released, the tension is adequate. If not, cleaning is likely required.

What tools are needed to maintain a Ruger rotary magazine?

You will need safety glasses for protection and a 9/64" hex wrench for the disassembly and reassembly screws. A suitable solvent like M-Pro 7 and a brush are also necessary for cleaning.

What is the correct procedure for reassembling a Ruger rotary magazine?

After cleaning, reinstall the screw and feed lips, place the rotor over the screw, and rotate clockwise. Reinstall the front cap and cap nut, ensuring the spring is captured. Wind the spring 3-4 turns clockwise before tightening the rear screw.

When should I consider replacing my Ruger rotary magazine instead of cleaning it?

If cleaning and proper reassembly do not restore the magazine's function, Ruger recommends replacing the magazine. Brownells offers OEM Ruger parts and magazines.
