The ETS Rapid Recognition System allows you to quickly and easily differentiate your mags. Many people mark their mags to identify what kind of load, or even what caliber, such as .300 blk, so you don't accidentally run the wrong ammo in your AR. And since our mags are Translucent you can see your color from any angle with a quick glance!
Each kit contains 2 followers and 2 base inserts. Enough to color 2 mags.
