The original Ruger 10/22 magazine release spring was only designed to retain 10 round magazines. With additional capacity magazines a popular modification, Tandemkross invented their Double Kross and Triple Kross springs to retain magazines that hold an increased number of rounds. The Tandemkross magazine release spring will retain factory Ruger BX-25 magazines and aftermarket magazines.

  • Replaces old magazine springs
  • Carbon steel construction

Tandemkross was founded by two software engineers who loved to shoot, but were tired of dealing with the problems so many rimfire guns have. After a frustrating day at the range, they created the idea for Tandemkross to solve their rimfire problems. The company is now one of the fastest growing in the rimfire sector.
