Mods: If this is repost please delete. Apparently some of the M4s etc. were failing in a recent battle in Afghanistan. http://www.foxnews.com/story/0,2933,563883,00.html?test=latestnews Is this a real problem we should be concerned about? Our Senator certainly thinks so. What struck me was that one guy was on his 12th magazine when the failures started. Was the M4 ever intended to handle that volume of fire? If you think it is a problem, what would you do about it? New platforms? Piston guns?
