Is it just me or is this an AR10?
Took this picture in Mexico last week. Didn't think anything of it at first, but then upon further examination, it appeared to be an AR10 or some variant like that. I didn't think these guys carried AR10's.
Took some more pictures of them as well. Saw a lot of M4's, FNC's, and G3's.
This is my little bro who asked the guy if he could take a picture with him.
