Does anybody sell them in different colors (i.e. magpul dark earth)?

Everything I find online is black.

Thanks

Every color you can think of in every type of finish. They are so ubiquitous that I won't post a link. That would only limit you if that is all you can find. Look around.

 

There are also places that will do custom colors and finishes to various specs. Judging by your question, that is not what you are looking for.

can always paint it yourself
