Enhance the performance of your Ruger Mark series magazines with aftermarket magazine springs from TANDEMKROSS. Over time, magazine springs can degrade, leading to diminished magazine performance and potential failure-to-feed issues. Avoid the inconvenience of a malfunctioning or absent spring during shooting sports competitions or practice sessions at the range. The Green Springs magazine springs for Ruger Mark series (3-pack) are shot-peened to ensure a significantly longer lifespan compared to factory springs. These upgraded springs effectively reduce failure-to-feed problems and serve as an excellent replacement for worn or damaged magazine springs. Available in packs of three, the Green Springs offer a convenient upgrade to carry in your range bag for on-the-go maintenance. The distinctive dark green color of these springs not only signifies your Tandemized pride but also helps differentiate them from standard factory springs.
