I ran across this while looking for some cheap 9mm mags for my M4 build. Thought I'd share. I'm not in any way affiliated with these people, just saw an awesome deal. http://www.ar15.com/forums/topic.html?b=7&f=24&t=479140 Mods, if you think this should be in the classifieds, feel free to move it. Just thought it would get better exposure here.
