At a glance:
- Shot-peened spring offers longer life than factory spring
- Reduces failure-to-feed issues
- Replaces old, broken mag springs
Upgrade your Ruger® Mark™ 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 Green Springs Magazine Springs for Ruger® Mark Series (3-Pack) 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.

Powerful Springs
Super strong springs, not sure why they are sold in packs of 3 when the follower and slide buttons are sold in packs of 2, but it's inexpensive enough to not seem like you are paying for something not needed. I like that they are green to designate which mags have the upgraded spring. A ton of force applied to the follower to ensure the next bullt will be presented in the correct position. The only downside is fighting the spring to get it into the mag, but expected when you get as much spring force as this provides once installed.

Green Spring for Mark IV magazine
The spring is difficult to install but with patience it will go in. It makes the Mark IV mag better.

Replaced too strong Mec-gar spring, a little better.

High performance springs
They are a bugger to get fit into the magazine, but well worth the effort.

A huge improvement... TUNE AND POLISH YOUR MAGS FOLKS!
I ordered a brand new #Tandemized Mark IV Lite race gun and bought 4 new magazines to go with the 2 that come with the Mark IV. I ordered the green springs, the +1 followers and the brass buttons for the magazines that arrived before the Mark IV. I took the time to tune and polish the magazines (Tandemkross has a great Youtube video that goes over this process) and the installed these upgrades... I promise, if you do it right it makes a TON of difference. I have had a number of .22 LR pistols over the years and all of the magazines felt cheap and very gritty. These are smooth as silk as long as you put a little bit of time tuning them. Easy to install all of the part upgrades and they run flawlessly! Don't just upgrade your guns and ignore the magazines, upgrade the mags too!

The Green Spring
I purchased the green spring because I was having problems with failure to feed with my new Ruger Competition Mk IV. After changing out the factory springs with the new green springs I noticed an immediate improvement. The installation wasn t that hard , but it does get easier with practice. If you use different types of ammo and you are looking at improving you gun performance, I would recommend trying the green springs it made my gun more enjoyable to shoot!
