Upgrade your Ruger® MK series magazines with aftermarket Ruger® magazine springs from TANDEMKROSS. Magazine springs wear and tear over time, reducing the performance of your magazines and resulting in failure-to-feed issues. Don't let an underperforming or missing spring derail a shooting sports competition or day at the range! The new "Green Springs" for Ruger® MK Series are shot-peened for a significantly longer life than the factory spring. The upgraded magazine springs reduce failure-to-feed issues and are an ideal replacement for your old, broken magazine springs. Sold in 3-packs, "Green Springs" are an ideal upgrade to keep in your range bag for easy maintenance on the go. The dark green color of the magazine springs is a simple way to show your #TANDEMIZED pride and keep your upgraded springs separate from factory springs. Supported Models:
