I did not comment on the weight of the M4. I stated that shooting any rifle standing unnsuported with no sling is hard and hitting anything over 200m in stated position is rather questionable. Even for a trained individual. I did also not make any comments about red dot optics. I was commenting on the use of (magnifying)scopes in a standing, unsupported position with no sling which will only magnify your instability, make you lose any situational awareness you may have had, force you to close one eye and use valuable time to locate your target within the scope. All negative factors. Some guy shooting 1200 rounds over the course of 18 months does not warrant the label real life stress test. There have been 2 major M4 studies conducted by the US Army. The dust test and the comparison test. Look them up. iirc i think 1 mis per 1100 is about what they concluded with. 10riflesx6000 rounds each. Oh but that isnt much you say. Well, how many M4 shots have been fired in Dayz total and how many misfires/jams? As for the incapacitation issues they are related to fragmentation. M193/M855 needs to be travelling at 2700 fps to reliable fragment(in human tissue). Fired from a 14.5" M4 they lose their ability to fragment at 50m. For comparison same ammo in a M16 has a higher velocity and doesnt drop below 2700 until 150m. That being said, being shot by anything isnt particularly fun, but being shot by something that fragments is a hell of a lot less fun. --- The disturbing failure of the 5.56x45mm caliber to consistently offer adequate incapacitation has been known for nearly 20 years. Dr. Martin Fackler’s seminal research at the Letterman Army Institute of Research Wound Ballistic Laboratory during the 1980s illuminated the yaw and fragmentation mechanism by which 5.56x45mm FMJ bullets create wounds in tissue. “If 5.56mm bullets fail to upset (yaw, fragment, or deform) within tissue, the results are relatively insignificant wounds, similar to those produced by .22 long rifle bullets – this is true for all 5.56x45mm bullets, including both military FMJ and OTM (open tip match) and civilian JHP/JSP designs used in law enforcement. As expected, with decreased wounding effects, rapid incapacitation is unlikely: enemy soldiers may continue to pose a threat to friendly forces and violent suspects can remain a danger to law enforcement personnel and the public. This failure of 5.56x45mm bullets to yaw and fragment can be caused by reduced impact velocities as when fired from short-barreled weapons or when the range to the target increases. Failure to yaw and fragment can also occur when the bullets pass through only minimal tissue, such as a limb or the chest of a thin, small statured individual, as the bullet may exit the body before it has a chance to yaw and fragment. Two other yaw issues: Angle-of-Attack (AOA) variations between different projectiles, even within the same lot of ammo, as well as Fleet Yaw variations between different rifles, were elucidated in 2006 by the Joint Service Wound Ballistic Integrated Product Team (JSWB-IPT), which included experts from the military law enforcement user community, trauma surgeons, aero ballisticians, weapon and munitions engineers, and other scientific specialists. These yaw issues were most noticeable at close ranges and were more prevalent with certain calibers and bullet styles — the most susceptible being 5.56x45mm FMJ ammunition like M855 and M193.” from: http://sadefensejournal.com/wp/?p=778 -- I comment on bullseyes(inner10) at 300m standing and you continue to talk about 100yard(93ish meters) shots in the black. I fail to see the connection. My point is that you should spawn into the game as Joe Average, with average shooting capabilities. After all you are just some random survivor with a flashlight in your pocket. For the M4 i have no problems with it being pin point accurate up to 500m or whatever as long as you are in a prone position, with support(bipod/log or any other object to rest it on), in breath, level with target and ignore climatic effects alltogheter. What I have a problem with is connecting realism to sprinting madmen, totally out of breath, with a gasmask on, 600 rounds of ammo and numerous cans of beans in the backpack stopping to take 300+m standing headshots in a split second.
