http://www.minutemanreview.com/2011/01/some-pictures-i-from-my-trip-to-mexico.html 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. Sorry, the pic may not be very clear, I already zoomed in and cropped it. Took some more pictures of them as well. Saw a lot of M4's, FNC's, and G3's. Below is a G3. This is my little bro who asked the guy if he could take a picture with him. He has an older M4 with carbine handguards, A2 upper, and two 30 round mags taped together. You can see another M4 and a G3 here as well... Wish I could have gotten more pictures.
