The Magpul M3 PMAG is so good, it's been adopted by the United States Marine Corps. The new color, Medium Coyote Tan, is now color matched for a reduced visual signature. The Sand color magazines are great for people who want to dip their magazine in Rit dye for custom color combinations and then good ol' Black is great for people who know that black goes with everything.
I'm not certain if Magpul is discontinuing the Sand magazines, but Palmetto is selling 30rd Non-Windowed mags for $9.99. Would that we could compete with that price but we're not a volume dealer. Thanks for checking in though!
