Description

Have a sluggish MKII, MKIII, MK IV, or 22/45 Ruger magazine? Chances
are the spring is fine but the actual culprit is the metal on metal
contact of the magazine button.

Not only does this make magazines hard to load but it can also cause
feeding problems by allowing the round to hang up before the bolt
closes. If your magazine has a gritty and rough feeling when loading,
we suggest using our Magazine Follower Button for incredibly smooth
operation. Our button is knurled for easy gripping but more
importantly, it eliminates the metal on metal contact providing easy
loading and trouble free feeding

The OLD style is a coarser checkering while the NEW style is finer. We have separate product pages for both
Fit’s all factory Ruger Mark Series Magazines
EXCEPT the old Chrome metal base Mark 1 Magazines
