Have you guys read the link from Teej?? Here are some excerpts... "The M4 and 3 competitors, including one M4 variant that can be converted from existing rifles, come out of a sandstorm reliability test – and the M4 finishes dead last, with more than 3.5x more jams than the 3rd place finisher." "After Action Reviews done by the Marines after the early phases of Operation Iraqi Freedom revealed that urban warfare scenarios made employment of the M16A2 difficult in some situations; Marines were picking up short AK-47s with collapsible butt-stocks, or scrounging pistols for use inside buildings." "Failure to maintain the weapon meticulously can lead to jams, especially in sandy or dusty environments. Kalashnikovs may not have a reputation for accuracy, or lightness – but they do have a well-earned reputation for being able to take amazing amounts of abuse, without maintenance, and still fire reliably. The Israeli “Galil” applied these lessons in 5.56mm caliber, and earned a similar reputation. Colt’s M16 and M4 have never done so." “USMC officials said the M4 malfunctioned three times more often than the M16A4 during an assessment conducted in late summer 2002 for Marine Corps Systems Command at Quantico, VA. Malfunctions were broken down into several categories, including “magazine,” “failure to chamber,” “failure to fire,” “failure to extract” and “worn or broken part,” according to the briefing documents. During the comparison, the M4 failed 186 times across those categories over the course of 69,000 rounds fired. The M16A4 failed 61 times during the testing." "Soldiers had their own comments, however, which were also included in the report and relayed in the magazine article: 3rd ID soldier: “I know it fires very well and accurate [when] clean. But sometimes it needs to fire dirty well too.” 25th Infantry Division soldier: “The M4 Weapon in the deserts of Iraq and Afghanistan was quick to malfunction when a little sand got in the weapon. Trying to keep it clean, sand free was impossible while on patrols or firefights.” 82nd Airborne Division soldier: “The M4 is overall an excellent weapon, however the flaw of its sensitivity to dirt and powder residue needs to be corrected. True to fact, cleaning will help. Daily assigned tasks, and nonregular hours in tactical situations do not always warrant the necessary time required for effective cleaning.” 75th Ranger Regiment member, SOCOM: “Even with the dust cover closed and magazine in the well, sand gets all inside; on and around the bolt. It still fires, but after a while the sand works its way all through the gun and jams start.” "A December 2006 survey, conducted on behalf of the Army by CNA Corp., conducted over 2,600 interviews with Soldiers returning from combat duty. The M4 received a number of strong requests from M-16 users, who liked its smaller profile. Among M4 users, however, 19% of said they experienced stoppages in combat – and almost 20% of those said they were “unable to engage the target with that weapon during a significant portion of or the entire firefight after performing immediate or remedial action to clear the stoppage.” The report adds that “Those who attached accessories to their weapon were more likely to experience stoppages, regardless of how the accessories were attached [including via official means like rail mounts].” Since “accessories” can include items like night sights, flashlights, et. al., their use is not expected to go away any time soon."
