Works well on ALL Magpul magazines, 10, 20, 30, 40 rd tested fine. Doesn't fit completely perfectly on Hexmags or aluminum mags, but acceptable.
Ordered a mix of two different colors and different amounts for each. Upon arrival...number counts were exact for both colors, all looked new and unused, shipping was super fast....same as always.
These covers are well worth their money. They serve two vital services. First they keep dirt and debris out of your magazine. Secondly, they push the bullets down just a little when installed and keep the pressure off the feed lips. If the feed lips aren't protected you may have a malfunction if you keep your magazines loaded for any extended length of time.
Perfect fit. Keeps the dirt and sand out. I leaded this first hand. You do want these for long term storage.
